It can be so frustrating to read STS research. Here are Bartscherer and Reinhart osf.io/rbyt6_v1/ Look at their flawed logic: Replication is *used as a career strategy*. The evidence? People were not known for earlier research. The clear confound? ECR’s drove the replication movement! 1/x

Paper drop, for anyone interested in #metascience, #statistics, or #metaanalysis! @clintin.bsky.social and I show in a new paper in JASA that the P-curve, a popular forensic meta-analysis method, has deeply undesirable statistical properties. www.tandfonline.com/doi/full/10.... 1/?

Can you make it easier than "the probability of getting results at least as extreme as the ones you observed, given that the null hypothesis is correct"?
Not Even Scientists Can Easily Explain P-values
P-values have taken quite a beating lately. These widely used and commonly misapplied statistics have been blamed for giving a veneer of legitimacy to dodgy stu…

Julia works quite well through Nix, but I need to do some further testing and make sure that the top, say, 100 packages build correctly for the list of dates I choose to support (rix::available_dates()). This will become my next milestone for rix.
looks it's coming sooner than expected

Researchers should not make claims based on exploratory analyses because the probability that these claims are wrong can be unacceptably high.

In all my years using #RStats, I’ve seen this kind of posts often. I think that R has evolved past the "traditional" way of using it which was installing it system-wide, and then installing packages system-wide. That worked, because there were less packages, but also because the kind of projects 1/3
*gets package errors because R version is too old*

*installs latest version of R*

*gets shinyapps errors because R version is too new*

New Sci Rep paper with odd-looking figures that don't look like any image conversion issue I've seen before. Has some AI vibes (fonts, line spacing of legend), but there are likely better explanations. Any thoughts?

@nature.com pls investigate (who copy-edited this)

How to move more and reduce sedentary behavior in daily life? 💡

Since September, during my teleworking days, I’ve covered 720 km (the equivalent of over 17 marathons), taken 1.2 million steps, and burned 50,000 Kcal — all during my working hours!

#rstat note to myself:
If you want to convert a factor variable that contains numbers between quotes (eg, "1", "3", etc) to a numeric variable while keeping the original numbers:

DO:
as.numeric(as.character(my_var))

NOT DO:
as.numeric(my_var)

The 2nd option returns variable level numbers!

Big news from Finnish publication forum. Almost all MDPI and Frontiers journals will be downgraded to level 0 and thus are not considered as properly peer reviewed trustworthy scientific journals.
