Interview: Refuting arguments about IQ bias & discrimination effects

This is a discussion between myself and Lipton Matthews.

Are IQ test biased?

Free Banking in Canada: Why We Need Good Historians

If one searches through old historical records, one will find economists praising the success made possible by the relative freedom of the Canadian banking system. Today one would hardly find modern economists holding such views. The most recent criticism of the free banking in Canada comes from Fung et al. (2017), which paper has been reviewed in Selgin’s well documented three-part series (I, II, III). This present article will also supply additional information.

The Use of Tobit and Truncated Regressions for Limited Dependent Variables

The OLS regression is a widely applied technique, and many variants of the classical regression exist. Among them, are the tobit and truncated regressions. Their use is recommended when the dependent (Y) variable is constrained in some ways. Both have a common feature. The Y variable is treated as latent variable (denoted Y*) rather than observed variable. This raises several complications compared to the classical OLS.

How to calculate and use predicted Y-values in multiple regression

Here, I will explain how to use the so-called “Y_hat” or predicted values of Y when doing regression (OLS, logistic and multilevel).

(Update 2017) This article is based on my paper: Hu, M. (2017). An update on the secular narrowing of the Black-White gap in the Wordsum vocabulary test (1974-2012). Mankind Quarterly, 58(2), 324-354.

Get (not so easily) introduced to R

I dislike R, unlike some other softwares I use, such as SPSS and Stata. It’s extremely error prone. But it’s free, and can do almost everything (e.g., a few things Stata cannot do and a lot of things SPSS/AMOS cannot do). As always, I will update whenever I learn something new.

Get (easily) introduced to SPSS

I do not want to make multiple posts on this topic. So, this post will be updated little by little (if I learn something new). Here, we have a list of essential commands for creating variables, making basic (and advanced) statistical analyses. I sometimes illustrate with examples using the General Social Survey data.
