用stata作factor analysis
The names f1, f2, etc., are arbitrary; the score command allows you to create new variables that could then be used in analysis. Stata also has a command for Cronbach’s alpha, providing a simpler way of combining the eight symptoms, assuming that all have equal weight: . alpha ...

dynamic factor analysis with STATA
Factor analysis technique is demonstrated using the principal component method in STATA, to compute the observed correlation matrix, estimate the factors, interpret factors using rotation procedure, compute factor scores for analysis.doi:10.1016/B978-0-12-405864-4.00006-5Suresh C. Babu...
From the last post in this series, you should know how to change between numeric types and easily change numeric data. We’ll now expand your type-changing skills to include changing string variables with two new commands.Read More Getting Started with Stata Tutorial #11: Editing Variables Usin...
The first consists of variables related to characters of sociability and to relationship with the handler, with expression of dominance/submissiveness and the second to characters of reaction to external stimuli with expressions of fearfulness/curiosity.Results of factor analysis led us to reject the ...
