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

Daniel Oberski @daob.nl · May 18

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.

We would be very interested in hearing thoughts and opinions. The global data landscape is changing dramatically and we need to think critically about what we do next.

Good luck Michel.

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.

Daniel Oberski @daob.nl · Jul 11

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

Daniel Oberski @daob.nl · Jul 11

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.

Thanks, this is *exactly* what I have been looking for!

Daniel Oberski @daob.nl · Jul 2

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??

Eurobarometer 38.1, 55.2, and 63.1. Provided without further comment.

Line graph showing the percentage of people believing "the Sun goes around the Earth" in 12 European countries, for the years 1992, 2001, and 2005. The averages for these years were about 10%, 30%, and 30%, respectively.

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.
