Regardless of your choice of α, the position of a point in relation to an arrow indicates whether that observation is relatively large, medium, or small for that variable. Also, although the special conditions mentioned earlier may not strictly hold for all α, the biplot still aids in ...
However, I just want to point out that in Step 2, you state: “To get it, create a new variable in which you subtract the mean from the original value, then divide that by the standard error.” I think this should say standard deviation instead of standard error to avoid confusion, ...

We used random coefficient regression models to estimate changes over time in the presence of unbalanced data (26). The prevalence of albuminuria (coded as an indicator variable 1 if yes, 0 if otherwise) was examined by multiple logistic regression using generalized estimating equations with robust...

improves if I replace in the PS logistic model categorical variables with a 'plain' non-factorized version (e.g. use "c.race" rather than "i.race" as a variable). This of course makes no sense as a rational "real-world" use of a variable, however the goal of PS analysis is to ...
As I remember it, you calculate them by multiplying each regression coefficient by the product of dividing its standard error by the standard error of the dependent variable. That takes up three columns in your spreadsheet of choice, and you do the sums in the fourth column. -- Clive ...
