IQ Regression to the Mean : the Genetic Prediction Vindicated
The IQ differences between blacks and whites lead to differences in sibling regression to the mean. The races regress to different means. Criticisms were made about the hereditarian interpretation of the differential sibling regressions. I will demonstrate that this phenomenon … Continue reading

IQ Regression to the Mean and Genetic Prediction : NLSY 97 SPSS Syntax
I must warn. It is probable that the CASESTOVARS command will not work because the number of variable exceeds 80 or 90. In this case, you should better stop the syntax before CASESTOVARS. Then, delete the variables you don’t need … Continue reading
