good example of a weak quasi-experimental design that is nonetheless convincing.

Not in regular lists, which would be a closer equivalent to the given R code IMO.

Interesting. How it thinks R should work *is* how Python works, and a lot of the coding benchmarks are very focused on python. Maybe that is the explanation?

Sending an email with this content to semnet (or wanting to) is all part of the circle of life Eiko. Generations of researchers have found out: semnet simply cannot change its nature, like in that scorpion story.

Anderson collected a lot more data than Fisher actually used for his example application in the LDA paper. What we did was feed some of that other data to many models at OpenML as well as the original LDA. I don't remember looking at overconfidence, but I'm sure you're right.

I know you're joking but we actually did this. Linear discriminant analysis was still the best :D

There is no 1-1 conversion between probit and logit coefficients. Probit coefs are easy to interpret if you standardize the LRV ("STDY"): the coefficient is the number of sd's increase for a one unit increase of the predictor. Easy to convert to probabilities by pulling the prediction through pnorm.

I.e. the sense is likely "more interpretable" rather than "obvious".

11.07.2024 14:58 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I think they don't mean "intuitive" in the sense of "obvious" but in the sense that it gives some extra information: From V and the pattern of zeroes you can tell which linear dependencies are taken care of. E.g. if there's both age and year of birth in X, those will show up in one column of V.

LISS has a basket option which automatically merges the time points/datasets you need. Is this what you mean?

(also the "time-invariant" background variables tend to be simple copies, except when they are actually repeated; so a single copy is often enough, depending on the time period)

I'm sure he would be delighted that he was able to bring down the number of his opponents to 1 in 5 in only 363 years!

(sorry for the wonky colors btw)

Quite. Hopefully it's all just measurement error from being confused by the question??

I may have been confused by "gold standard": if you're doing observational data-causal inference but say you'd prefer to have an experiment, that implies you think that experiments are better. That crossed wires in my brain with your criticism of papers claiming experiments are not better.

Ok thanks! I think I still don't fully understand the "temporarily embarrassed" bit, but those do sound like extremely vague arguments. (which issues, what complexity, what context, why is it important, how does something else account for context?)

Even though LLM seem to me to be able to do this job reasonably well & more flexibly, there could be another reason to use regular expressions, when statcheck is used to check articles submitted to a journal: it encourages people to write the statistics in APA style.

This is my experience too - seems to work fine as long as you give it precise instructions to use Python etc. There are some ways to force it into actually evaluating numbers even more.

Hi Julia, this sounds like an interesting discussion, but I do not really understand what you mean. Which articles are you referring to? What kind of arguments do they give? And what do you mean by "temporarily embarrassed experimentalists"?
