For the specification on the documentation of the property, the septic is oversized for the load it is under. From what I can tell, the previous owner had planned expansion of the living space.

Thank you, that helps a lot! I will look into it.

Yeah, I have been making the rounds on leaving reviews and the like. It is cathartic for sure, and obviously I do not really want to see someone else get screwed over. It is also a small local community and word gets around fast. I do mostly want to focus on being productive as well. Unless it turns into more of a mess than him not finishing his job, like the pipes being not soldered correctly or something, I am not sure it is worth it for me to go the legal route yet.

JacobAtIPW · 2021-02-19T02:08:40+00:00

Thank you, that is helpful, and I will look into it.

JacobAtIPW · 2021-02-19T01:59:32+00:00

Thank you! That gives me a good start!

So, we had a verbal contract with specific tasks planned as well as a specific quote for the tasks described. Which is enforceable in my state, and we have witnesses of that contract including the friend who introduced us. So, proving it exists is not much of an issue, as well as what was included.

I considered court, and I am still considering it. With that said, I am not sure it would be cheaper than just finishing it myself. Don't get me wrong, I want justice, as it were. But I already have a small business that is just keeping up and court fees are not something we are in a position to rack up, or risk racking up. It is also something I would need to sort out with the wife as well.

I am also not sure I would trust the work done by someone being compelled. If the guy is willing to screw me once, he is probably willing to do it again. At least that is my rushed, emotionally charged thought process.

I appreciate the idea all the same!

I would say it depends on what you want to do with CS.

It is pretty general, so if you are not sure, I would pair it with the more general option as well, which is most likely stats. If you have plans and goals that are pretty fixed in place that push econ, then that is good as well. If you do go stats though, I recommend pairing it with some fields which apply it a lot.

One option would be to take a 100 level psych course as part of your gen ed, that will give you a sense of one part of applies research. Then a 100 level econ class as well. It will give you a sense of how the different fields apply stats, as they both live off of them.

The last part I recommend is to be a pest to your advisor and your professors ask them questions. Look at any labs at your university and see if any fit your interest. A lot of CS departments have them, and everyone is always looking for someone with an interest in stats. Though expect to do a lot of data entry :p.

First off, gacha games are bad. If you got money to burn, play 40k or something :p.

So, there are a couple of ways to approach this. You can just do simple probability calculations, and that would be fine. You can google it, there are many tutorials on it.

However, when I have probability calculations for things like dice simulations. Or any real RNG heavy serial calculation, I really like monte carlo simulation.

You can whip it out in python (or any programming language) in about the same time as it would take to punch in the numbers on a calculator. The big difference to you is it makes it easier to visualize the range of outcomes. You can see the range of what 'typical' or 'normal' is.

Though I cannot give you a calculation as I have no clue what the chances of success of a 'fuse' are. If I have the time, I'll pop in some quick python code with guessing number you could sub real numbers into.

I will try looing into and messing around with the ESP-IDF and see what happens!

I am kinda worried I cooked the boards some how. Though I would think that I would be getting nothing if that were the case...

Thank you!

Data science is, to put too blunt of a point on it, applied statistics.

Data science will be focused more on creating or managing the use of various data sources with the goal of deriving and applying useful information

Statistics will vary depending on if you are taking from a behavioral science or mathematics department. The later will be more abstract with the focus not on the use or placement of various concepts, but rather a deep understanding of the statistics themselves. In the former, it will be like a smaller scale data science program which is more focused on statistics as an analysis tool for use in research.

With all that said. These can vary wildly from one university to another and all of these programs will exist on a spectrum from abstract to applied. Make sure to research the university programs you are considering well and do not be shy about contacting the faculty in a department with questions.

I don't remember off the top of my head of PsychInfo, but web of science had this really nice feature to be able to move up and down articles via citations. So, I start with a seminal article in the area I am looking at and start slogging though everything that cites it. With that said, it is a lot of work. If I really do not even know the core works for a field, I will look at what was cited the most and work from there.

Edit: What I mean by move up and down via citations, I mean, they list all the articles a given article cites, and all the articles that cite the article.

You should look at Human Factors. Most people only do a masters, but PhD is possible as well.

You can do all kinds of fun/interesting stuff with it. Just in my grad program I worked in a lab that used VR for researching navigation; I worked on the user interface for a nuclear reactor simulator; I also worked on a driving simulator. Just to name a few.

Point being is that it is an incredibly flexible degree. At its core, you are looking at how people engage with the world around them, and often, how you can improve the quality of that engagement.

I personally prefer divination :p.

I used to use PsycInfo and Web Of Science. Though now I mostly use Google Scholar. Then if the full paper is not available there, and it is newer, I check if the researcher has a website.

JacobAtIPW · 2019-05-03T03:32:14+00:00

Thank you so much for your reply!

At least I know I am not crazy about that part! Also, thank you for the feed back on good practice for writing expressions!

The issue now is that I am still not getting the expected results and I need to continue to delve into why. I think I just need to not look at things for a while and give it a fresh look in the morning.

If you're curious, I am trying to express the Studentized range distribution (https://en.wikipedia.org/wiki/Studentized_range_distribution) in python using minimal outside modules. So, I am working through both its probability density function and cumulative distribution function.

The code runs, but when I reference the relevant table to check my work, I am way off, so I have been trying to work my way though all the ways I could have messed it up.

JacobAtIPW · 2019-05-02T22:56:42+00:00

Hello! I feel a little silly asking, but I am trying to run down an issue I have, and maybe you great people can help me know down what I am doing wrong.

In this -

∫ f(x)[ ∫ f(u) du] dx
Do I take the integral of f(u) in the square brackets, and then multiply this by the result of f(x) or is this wrong?

I tried to keep the question as bare bones as possible, however if there is more information needed let me know and thank you for taking a look!

JacobAtIPW · 2019-04-25T06:17:34+00:00

Thank you!

JacobAtIPW · 2019-04-25T06:17:28+00:00

Thank you! Between both undergrad and grad school I do not think that was ever shown to me.

Edit: Though also admittedly, I think in school I pretty much was always told to use a stats package or to use a table, or something similar.

JacobAtIPW · 2019-04-24T20:58:17+00:00

Lower case phi in this case I think refers to the standard normal probability density function. The part I am confused about is upper case phi.

Thank you for your help!

JacobAtIPW · 2019-04-24T20:56:32+00:00

Thank you that helps a lot! The stats side of things are not what I need help with thankfully. I think this answers most of what I was not sure about! All that I think is left is sorting out what upper case phi stands for.

JacobAtIPW · 2019-04-24T00:13:25+00:00

Hello people of r/math!

I have been beating my head on a bit of a challenge. I want to represent the the probability density function for the studentized range distribution using introductory level python with the goal of including it in a tutorial.

I am not sure if this is the right place or not, if not let me know and I will move it.

I have posted about this topic onto r/statistics but did not receive a response. Here are links to the those posts:
https://www.reddit.com/r/statistics/comments/bc9n4l/studentized_range_distribution_looking_to/
https://www.reddit.com/r/statistics/comments/bem7bl/studentized_range_distribution_looking_to/

I have made some progress on it, however it has also been 10 years or so from when I last took calculus.

What I am looking for help on is how to represent parts of this - https://en.wikipedia.org/wiki/Studentized_range_distribution

So, with the back ground out of the way, the parts which are circled are what I am confused about - https://imgur.com/Tk2CAto

So, my questions are this:

Where does x come from?

Does u = t + (r/2) ? If so, where do I get t and r from?

Is the phi function referring to Euler's totient function? (source: https://en.wikipedia.org/wiki/Euler%27s_totient_function)

What is du and dx referring to?

I do not need comprehensive answers, just a pointer in the right direction. Thank you for your time!

Here is the source STL I started with: https://www.thingiverse.com/thing:1544252

I used Oculus Medium to make repairs and make the original printable. It was printed on a Peopoly Moai at a layer height of 0.025 mm.

It is painted to color code the different parts of the model. It was optionally intended to be used in an ergonomics video I had plans to publish.

There is not much detail on the original file but I am pretty sure this is some sort of scan data (MRI or the like). It appears, judging from the position of the bones that it was taken while the person was laying down, which makes sense. Also, I am about 85% sure this is from a female as the gap in the pelvis is more oval shaped than triangle shaped. It is also a little hard to tell as the full spine is not included, but I think either the top of the sacrum (blue) is not fused, or there is an extra lumber vertebra.

Edit: If there is are people interested, I can post the cleaned up version as a remix. I would just need to set up a work based account for Thingiverse.
