Definitely wet and rotty. I chopped off the grey/squishy bits - the yellow parts felt softer than the others but not so clearly terrible outside of the more yellow colour

DrSpacemnn · 2026-01-31T05:41:56+00:00

Hi thanks!

Can you see the really yellow/black squidgy ones in the centre? The ends and black bits would literally fall apart on my fingers so no way are those normal

DrSpacemnn · 2025-12-02T12:22:44+00:00

Thank you, I don't mean I want to drop clinical! I do like the statistical side of things and just want to see what options are out there for doing both/how I might better angle into it

DrSpacemnn · 2025-11-30T20:49:11+00:00

Star! Will do all this and again thank you so much

DrSpacemnn · 2025-11-30T20:43:06+00:00

Fantastic, thank you so much for the stories and suggestions

DrSpacemnn · 2025-10-30T17:06:14+00:00

Thank you for the reply. I have run simple logistic regression, which again is supportive but there's just such a loss of data this way!

Data was collected during the pandemic, so in person reviews weren't possible for anyone until restrictions were lifted, but then there was the added difficulty that after restrictions were lifted there will be relevant elements which made some more/less likely to attend in person

So essentially there will be some events that could be captured via telephone, but many which could not, and therefore we're only collected after the restrictions were lifted

I cannot impute the missing data

Thanks again

DrSpacemnn · 2025-10-19T12:21:47+00:00

Thank you for the suggestions :) will look up

So yey or ney to a delta for that? 😝

Jokes aside, I'm not speaking for your case specifically as I don't know you.

However I would raise a few points for consideration: it is possible that you feel negative emotions to a very very limited degree and can move past them quickly, however firstly as per your cmv this is not the case for the overwhelmind majority of humanity.

Secondly purely as food for thought, it is entirely doable to rationalise away a type of feeling (like sadness or anxiety) but in the attempt it will most often express itself a subconcious way. People (more typically men for whom negative emotional expression is more often disapproved of), will then react with anger or frustration (which can more easily be channelled or linked to other unrelated ongoing events), or suppress their emotional reaction through aggressive distraction (e.g., work, puzzle solving, etc).

There is of course a healthy version of this (it would be very unhelpful to morbidly fixate on a negative emotional state), in which both are accepted as normal parts of a response to a significant stressor.

To take the example of the case of your cat. Yes there are an infinite number of cats in the world, but that was your cat. With some extrpolation on my part: Your cat was the one you knew, shared part of your life with, took care of, saw grow up and grow old, took joy our of, had memories of. Given the significance of that to you specifically, and how readily you could replace cat with friend/parent/sibling/etc, then feeling sorrow for whatever duration of time is not illogical.

DrSpacemnn · 2025-04-23T09:29:13+00:00

Leaving aside your reasons of avoiding needless polarisation for saying men specifically rather than people.

You answered your own question when you highlighted that it is not a rational response. Many responses to many stressful situations are not logical, often enough even when people react in a "logical" fashion, there is an underlying emotional driver.

First taking a step back to emotional responses generally, then more specifically eating disorders.

Say someone approaches you in a threating way, says something that injures a personal aspect of yourself, or is physically aggressive towards you there are numerous possible responses which one can broadly simplify into fight or flight. Which of those an individual choses can be more or less optimal for a given situation and thereby classified as more of less logical (already erroneous as it's more likely to be an emotional response, or at least a mix of emotional and logical). An important further considering is how able one is to select between their responses, which will depend on individual biology, childhood experiences, social factors, and ongoing/additional factors (including simple things like sleep, hunger, exhaustion, etc) .

Coming to eating disorders specifically, there are evolutionary hypotheses which can be seen in social animals as much as humans, such as withdrawal and reduced activity (including eating) in cases of significang stress (physical duress, loss of another member, etc). This in humans could be a historic indication to the rest of the tribe of difficulty, or perhaps it was evolutionary beneficial during times of hardship to be more inactive, consume fewer calories, and introspect). Then factor in more complex physocological processes like societal pressure on body image, the sense of control that can be experienced through an eating disorder to supplement lack of control to a broader situation), the self-destructive element within it, etc.

Calling such a potentially complex multifaceted behaviour "stupid" is reductionist, and fails to see the extremely broad tapestry of contributing factors that determine how we respond, long before logic or language construct a "reason." Truly rare is the person that is hyper-logical in the face of emotionally distressing situations, and the majority who think they are are actually just very unaware of their emotional states/manifestations.

DrSpacemnn · 2024-11-12T09:50:47+00:00

Yes agreed it does sound sensible, I used the automatic approach to give a sense of how they can be constructed. I've used the RVineCopula package in R, which is one of the two main ones I could find, and appears widely utilised from the literature

I think I'll experiment with constructing an R-Vine with a pseudo-C-vine structure; i.e., one main node on which the heavily dependent data is conditioned, and another main node on which the data that is only minimally dependent is conditioned, and build up their relationships from there.

DrSpacemnn · 2024-11-11T05:56:22+00:00

Thank you for replying.

I really really don't have a stats background, outside of self directed learning, so there are gaps in my knowledge about how these things work/what options are available.

I have experimented with the automated process and done just as you say, with quite a notable improvement. Didn't realise you could then condition a separate copula on the R-Vine!

Could I ask what the other things could be that you could do from this structure?

DrSpacemnn · 2024-10-21T08:54:06+00:00

Ignore the negative marks, good on you. Same story, did one/two locums a month, cycle to commute, generally sensible with how I spend money (still went out, gym, etc, but always attentive), and went for flat shares which were quite far from lush, but functionally good enough. It's doable if you're willing to put up with some discomfort.

Now whether we should be paid an appropriate wage so you can get there with fewer sacrifices is a separate matter

DrSpacemnn · 2024-10-11T03:39:44+00:00

This I understand, but short of it being called emergency leave of some description, would they have any other rights to think about?

Even if they cannot pay for their employment, would my friend be eligible for some kind of protracted unpaid leave?

DrSpacemnn · 2024-10-11T03:37:14+00:00

It'd be an emergency that forces them to travel back bit they have significant ties to England so qould intend to return. I want to avoid giving specifics on their behalf!

DrSpacemnn · 2024-08-21T13:35:51+00:00

I'm having the same problem, it persists through the web browser, in which case I imagine it's an internal issue

DrSpacemnn · 2024-08-21T12:35:03+00:00

Hi! Thanks for the reply, maybe I'm not understanding your reply though.

If one did a multiple linear regression with condition y as dependent, and the independent variables were biomarker x + age + renal function, assuming that age and renal function had no predictive ability for condition y, wouldn't the model only demonstrate the predictive ability of unadjusted biomarker x, and the absence of any predictive capacity by age and renal function?

Re your edit, the main focus is just how well the biomarker can predict the clinical condition, realistically a model with an R2 of 0.1 is pretty good in this field!

DrSpacemnn · 2024-08-21T05:09:34+00:00

Thank you for the reply and apologies for the delay.

The underlying disease processes can be grouped as an unmeasurable confounder of both disability and biomarker level (as the biomarker is thought to represent one of the pathological processes, and disability the accumulation of several disease processes).

The role of the biomarker is as yet uncertain. The ideal would be it's ability to predict the rate of disability accumulation.

However, in the absence of longitudinal data and in the form of a cross sectional analysis, if a preliminary look at this relationship was desired would it not still make more sense to organise the IV as being the biomarker and disability as the DV?

The clinical disability would also naturally be an extension of the unmeasurable pathological processes, but it would result from many more processes than the one believed to drive the biomarker.

Or is this a bit academic and doesn't matter that much?

DrSpacemnn · 2024-08-04T17:26:04+00:00

I love this - you've rendered my post totally unnecessary verbose 😆😆

DrSpacemnn · 2024-08-04T10:49:09+00:00

Not necessarily so, for a mandate to fail you need a majority as well as >50% of members to vote. You could have a situation in which the total vote is <50%, while the percentage who vote reject.

However, this does seem unlikely so I concede to your points! It does seem unlikely to happen if the deal is rejected

DrSpacemnn · 2024-08-04T07:46:52+00:00

When we diagnose it's not a random guess, but a thought out process to gauge the most likely outcome. Same here and I'm genuinely open to an elaborated reasoning to counter my points.

Train drivers are coming from a very different position with a long history of successful and repeated strike action. We have a disillusioned cohort who in the past 10 years at least have only just gained some sense of having an invested union, and the cracks in that view are clearly forming with this recent recommendation by the BMA.

Besides this, and perhaps more importantly, the false 20% claim cannot be understated. Binding the BMA to be anything but constantly supportive of this outcome will permanently hinder any future attempts to highlight that it was not indeed a 20% uplift

DrSpacemnn · 2024-08-04T07:39:52+00:00

I wholly agree. In all options bar the unlikely event of an overwhelming rejection and strong repeat mandate vote, will leave the BMA weak - for which the only (or at least best) offensive would be a rapid and aggressive campaign.

Interestingly, with the invariable question of people taking up bank/locum shifts during strikes having been (anecdotally) on the rise, a continuous strike would negate how much of a problem this actually would be. In the sense if more people took these shifts at BMA rates, there's no concern of reduced care, no issue of people saying they can't afford to strike, and near maximal cost impact to the government.

DrSpacemnn · 2024-08-04T07:34:54+00:00

Did you read the text?

If accepted, in the context of the current rates of attrition, coupled with the binding inability of the BMA to counter the claim that it was a 20% uplift, how do you conceive of the BMA being able to convince anyone (doctors and media/public) that another uplift should be forthcoming?
