New working paper: Some methods for analyzing and correcting for spatial autocorrelation

Post your review over at the OP forum: http://openpsych.net/forum/showthread.php?tid=251 Title: Some methods for analyzing and correcting for spatial autocorrelation Authors: Emil O. W. Kirkegaard Abstract A method for examining spatial autocorrelation based on distance scores was examined and found to be deficient.

Rationality and bias test results

I’ve always considered myself a very rational and fairly unbiased person. Being aware of the general tendency for people to overestimate themselves (see also visualization of the Dunning-Kruger effect), this of course reduces my confidence in my own estimates of these. So what better to do than take some actual tests? I have previously taken…

Web scraping with R using rvest & spatial autocorrelation

Scraping with R Although other languages are probably more suitable for web scraping (e.g. Python with Scrapy), R does have some scraping capabilities. Unsurprisingly, the ever awesome Hadley has written a great package for this: rvest. A simple tutorial and demonstration of it can be found here, which I the one I used. To do…

Betas and residualized variables / does non-g ability predict GPA?

@JamesPsychol Those results don't look real to me. Betas are never exactly identical across models. — Emil O W Kirkegaard (@KirkegaardEmil) September 8, 2015 @JamesPsychol @KirkegaardEmil FSIQ is uncorrelated with the residualized factor index scores, so its beta doesn't change across models. — Timofey Pnin (@pnin1957) September 8, 2015 Let’s test that. Since we don’t…

Looking for commenters for our Admixture in the Americas target article

We will be submitting the Admixture in the Americas article (first part) to Mankind Quarterly as a target article. Therefore, we are looking for people to comment on it. We are looking for people with substantial knowledge regarding the question of ethnic/race and national differences in psychological traits, primarily cognitive ability, and socioeconomic outcomes. Especially…

Sociology/political science journal?

I am considering starting another OpenPsych journal focused on sociology and political science. This is because I need somewhere to publish my S factor papers and I want an open science journal, with open data, code, and review. My guess is that such a journal does not exist right now, so I will have to…
