@KirkegaardEmil @PhDefunct I don't understand the table. Why are 1st and 2nd measurement equal in first line?
I have made a visualization for understanding regression towards the mean. http://emilkirkegaard.dk/understanding_statistics/ …pic.twitter.com/xIEAtQ0Dzi

@sTeamTraen@PhDefunct Both are equally good measures of the latent variable. -
@KirkegaardEmil@sTeamTraen As you slide the reliability lower, the 2nd meas.occasion correlates less highly with true score than 1st -
@PhDefunct@sTeamTraen It is because of sampling error, which still exists with n=10000, but it is not very large. -
@KirkegaardEmil@sTeamTraen Ah. Thanks!
