In the placebo group value A is x %. You want to know if in the treatment group value is at least x + 10 %. How many people do you have to test? (Without getting into details about study design. :-) Anyway, you don't think power analys

How would you answer the question how big a sample has to be to measure an effect of a certain size?

A Nazi's wet dream. In the submitted article, they say that 10% of the data was used as test data set. I cannot find that info in the orig article. After skimming through the paper, it seems to me the reported accuracy results from the

That's a lot of text + code for a rather trivial task.

I hope you are aware that those introductory courses give you a rather high level view of things and often hide any problematic points from you. It's like driving and only learning to know about the accelerator.

With all due respect but this is ridiculous. I guess you forgot the irony tags. Most (now famous) stoicists where governors or in high ranks. As such they were utmost conservative. Stoicism is the art of being governable despite of you thin

So where is the International Stoicist Front fighting today against the evil in the world and the suppression of the poor? Oh, they aren't. They are working for international cooperations in a middle management position. Why is meditat

I don't know much about Chinese history but it seems to me that some sort of China as a unified entity existed for 1000s of years. In Europe on the other hand, borders were much more combated due to expansions of this or that empire (R

What are you missing? Some convenience at the price of another dependency. A hip name. That vague feeling of hipness. Anyway, packs now are the official way to manage your rtp.

WRT julia's type system: I still don't get it. Is Julia dynamically or statically typed? Are type errors detected at compile time (or since it's jitted when loading a file) or at runtime (i.e. when the code is executed)? I pe

While these tips are good per se, in retrospect I don't think it's that a good idea to tie your muscle memory that much to a single piece of software. I'd say enjoy the cursor keys. Moving around in insert mode is ok too.

AI again? Expert systems are around to support medical doctors' decision making for 2+ decades. Studies demonstrated that doctors can use them to improve their decisions. Hardly anybody uses them in practice. In real life, medical info

You didn't really provide enough facts to actually answer your question. In general, I'd present realistic scenarios, dilemmas etc. and talk about those. What would you do etc.?
677.
by stewbrew 10y ago
That would be so because with R you get access to a myriad of statistical packages or because the functionality of numpy etc. is already included? IMHO the only real shortcoming is the lack of 64 bit integers, which is of course ridiculous.

wrt assignments: = does assignments too but not eagerly. It's used for late bindings. This isn't a matter of style as your reference to adv-r would suggest but a different use case. I wish people would spend more time reading the

Isn't this how science works? Even if "evidence" doesn't "vanish", your understanding of it could be invalidated. Truth is a temporary agreement.

Once you discuss rulesets and guidelines, it's probably rather a craft. Just because it looks like art from the past century doesn't make it art.

I think the more interesting questions would be: - How to write a novel that is actually a worthwhile read? - Why should you invest your time into an endeavour that will most likely fail and have no significant outcome?

You typically import it like: var foo = require('foo'); The lib's functions are accessed solely via the foo object. There is no interaction when different libs require different versions of a lib because the access th

Which one allows to import multiple versions of a lib/module/package with different versions? (Not primarily but also an issue of the package manager.)

Does any of these support out of memory data? IIRC dplyr can use a db as backend but I could be wrong. Anyway, I wonder why not just use a db & sql for more demanding data munging?

The hypothetic example of "people with mental problems" was only part of my statement. The citation above doesn't cover mental problems as result of concentrated social deprivation you only see in cities.
