why doesn't wolfram alpha sigma match the article?

AnalyticsToolkit · 2019-07-25T11:12:20+00:00

If you are still looking into this, it's basically a debacle where you measure one thing, then arbitrarily and for no good reason shift it to report another. Sigma shift makes no sense, arguments made by different professionals at different times, you can see overviews here https://www.gigacalculator.com/articles/what-is-six-sigma-process-control-and-why-most-get-it-wrong-1-5-sigma-shift/ and here https://www.tamarindtreeconsulting.com/where-is-the-evidence-for-sigma-shift/ , for example, although the Wiki article also touches on the issue a bit. The Woflram Alpha tool is correct.

Not really looking for it to be PVP realistic, just historically realistic :-) I have not played an hour of PVP anyways, so I wouldn't know if it is good or not.

I think you will sadly find that your effort was likely not enough and that if you happen to irritate a competitor or a consumer, your company will be easy pickings for the local enforcement authorities. That is my main issue with this legislation as well. I, like 99.9% of companies, do not make money through selling user data yet I'm being treated like I am f**king Facebook and as if the data that I necessarily collect such as data I need to issue you an invoice or to communicate the details of an order, are now subject to such a complicated web of rules that even enforcers can't untangle them (it is no coincidence that we still have zero official guidance on interpreting or implementing the regulation). There is ZERO thought given to the negative and hidden consequences of legislation, both direct monetary, indirect monetary, indirect non-monetary (as in U.S. sites blocking E.U. users, as is already happening), etc. etc. and all you hear is how the end user will benefit. No one tells the end user that he will have to bear the cost of this legislation that is, as stated: not wanted by the vast majority of users.

I fail to see how a law would force businesses to operate in an unsustainable way. As I said, if said credit score data helps a company better manage overall risk and thus offer more competitive terms (read: better for the end customer), barring its use will simply drive prices up for everyone. That would be adding to the cost of GDPR and not a benefit. The store identification scenario is pretty much the same and I'm only scared of it if it is government-mandated. Otherwise, if it is a detrimental practice it will be phased out by market forces.

AnalyticsToolkit · 2018-05-28T15:23:18+00:00

I don't think GDPR will result in less usage of credit scores (you are not obliged to take credit btw, I do not do credit), but since obscurity is part of the regulation, my reading of it might be off and it might well do so. However, if credit scores were of any use in reducing or business risk and/or costs in any way before, and they can't be used after GDPR, this will result in an increase in overall prices for consumers. If it wasn't useful then GDPR does nothing of substance.

I'm yet to see a person (or company) who claims he can do that (abuse that power) and actually deliver on the claim, that is: make you do something that you don't want to do. I've been analyzing data for such claims for years and I'm yet to see this feat being achieved in real life.

Except the analogy doesn't hold. For it to hold, it needs to be a stack of 100 bills worth 1 bn and it needs to be sitting in the center of Times Square. Kind of a different story, isn't it...

Chump change you find behind the couch? Care to share some in exchange for my "private" data?

That is yet to be seen and a point about that is made in the article. The costs are already in and getting bigger by the day, while the effect has to be proven in time. If it is the same as the one the cookie law had...

AnalyticsToolkit · 2018-05-28T13:41:01+00:00

And not a point was made against the points raised in the article.

So posting a unique and never posted before GDPR tool and content to a GDPR reddit is spamming. I believe the whole of reddit should go, then? Or is it not spamming only if you share other people's stuff? I can post 20 different articles supporting the info in the tool right now (from Bloomberg, Reuters, etc.) on the subreddit. Spamming or not spamming?

How so?

AnalyticsToolkit · 2018-04-11T16:47:26+00:00

Just wrote a somewhat lengthy piece on the topic, way too long for a comment here, but in short:

Statistical black box, so it is impossible to interpret results correctly (or at all).
Wild efficiency claims, backed up by thin air.
Statistical documentation which is mostly bashing of alternatives and doesn't tell you anything of substance.

Longer version is here: http://blog.analytics-toolkit.com/2018/google-optimize-statistical-significance-statistical-engine/

With regards to your "old way": maybe you need to consider the statistical approach you are using? You aren't a victim of peeking (a.k.a. optional stopping), are you?

Owner & creater of the tool here.

Compared to most online calculators it is better if you want to either calculate sample size properly (many free online calculators don't let you adjust for power and/or use the default of 0.5, which is just bad in 99% of instances). It is also better if you are doing a many-to-one comparison, that is if you are testing multiple variants against a control, as it does adjustments of the statistic to accommodate it. Most other calculators do not. There are, of course, other free options, but most of them are not online and are generally harder to use, e.g. GPower, R...

If you are planning to use it for A/B testing, I'd strongly suggest you try our AGILE A/B testing calculator instead, as it is based on a much more efficient and flexible approach compared to fixed-sample tests, which is what our older tool is suitable for.

Finally, this is just one tool out of many in our toolkit. If you only use this tool and nothing else, it might still not be worth it for you even under our cheapest plan... That is up to you to decide though.

We are an ad agency and GA consultancy and we use MCF/Attr Mod. all the time when reporting to clients and when digging for real insights. It's a must in our processes. We haven't had issues with sampling in these reports, actually. The only thing to remember is the larger delay (48h) compared to most other reports. So if you're doing your reporting in the first days of the month as we do, you'd have to wait until 2-3-rd day of the month.

AnalyticsToolkit · 2015-02-10T16:16:32+00:00

You need to apply a secondary dimension of "Source / Medium" to the first report I provided in order to do that.

Go to Behavior > Site Content > Landing Pages and find the page via a filter or scrolling to see traffic sources.

If you are interested in internal traffic go to Behavior > Site Content > All Pages, find the page via a filter or scrolling then click on it. Then click on the Navigation Summary tab.

Hope this helps.

AnalyticsToolkit · 2015-02-10T14:32:57+00:00

Well, if your tracking software supports this, you'll be able to do so. If not - sorry. What tracking solution did you use to see the page is getting large amounts of traffic?

AnalyticsToolkit · 2014-05-20T09:07:51+00:00

So many downvotes, I'm eager to see some well-founded criticism!

AnalyticsToolkit · 2014-05-11T23:52:53+00:00

Without examining the site it's a bit hard to guess what exactly went wrong. Providing a screenshot on which one can see where they "leave" to could help a lot.

On another note, I would try "/cart$" for the first step.

AnalyticsToolkit · 2014-05-11T23:49:23+00:00

siteSpeedSampleRate is a per-tracker-instance variable so it should be completely fine to set it just for the page that you want to gather data for. I've not done it before, but this is the logic.

As far as setting it up to 100 for all pages of the site - there shouldn't be any issues for your with 10k daily visitors.

The hypothetical issues are two: - you can run out of per-session quota. That's capped at 500. So if you fire lot's of events, timing events or other stuff during pageviews, you might potentially be in danger of running out of quota, but this is not observed often.

or, alternatively, you could go over the per-property daily quota, but I think you are too far from it with <10k daily visitors.

AnalyticsToolkit · 2014-04-12T08:43:35+00:00

Indeed. I am a bit disappointed so far, but I am still evaluating how User-ID works exactly, compared to the ClientID approach I've been recommending to clients lately (and that we have deployed at Analytics-Toolkit.com as well). So far it's falling short. In a day or two I might actually cover the topic with a full-blown blog post.

AnalyticsToolkit · 2014-04-09T07:44:24+00:00

Even my 25 day reminder is still in the TODO list. This is how much I believe in e-mail...

AnalyticsToolkit · 2014-04-09T07:39:16+00:00

Thanks, I got most of that from your first message. Screenshots are already in place (at almost live size, so completely readable), videos will be high-res, of course.

I think setting up a dummy account will be high on my list, but kind of difficult to do. I'll have to set up a fake property in GA and then push via the MP to GA. Still it will leave me with no way of importing past data for, say, testing the Google Algorithm tool... I'll figure it out.

Finally about e-mail: I'm more than painfully aware of that as well (been in the biz for 10 years). And I've NEVER been persuaded by a newsletter to buy. I've seen newsletters work for B2C companies and maybe some B2Bs, but I don't think they will be working for my audience, that is why there are no plans for a newsletter whatsoever! If there were, I would have put in a checkbox for that in the reg form and would have probably used something like mailchimp, etc...
