1. simulating data for factor analysis

Hi I was wondering if any one can recommend a book or website that explains step by step how to simulate for factor analysis I manged to find few sources online like this one https://personality-project.org/r/book/psych_for_sem.pdf However It was too complicated for me any recommendations?
2. Skewness coefficients

Thank you for the help, I found what I was looking for
3. Display equation to predict z-scores

I am trying to formulate prediction equations for normal lung function. The most suitable model has BCPE distribution As shown below summary(bcpe) ****************************************************************** Family: c("BCPE", "Box-Cox Power Exponential") Call: gamlss(formula = fevfvc ~...
4. Skewness coefficients

how to determine standard error of the estimate of this model please > summary(mm.nofvc) ****************************************************************** Family: c("NO", "Normal") Call: gamlss(formula = fvc ~ log(height) + pb(log(age)), sigma.formula = ~pb(log(age)), family =...
5. Skewness coefficients

So there is no skewness coefficients right? Another question please, how to display standard error of the estimate of the model?
6. Skewness coefficients

Hi I'm using Gamlss to formulate prediction equations. The problem I am facing is that when the model is normally distributed I can't obtain the skewness coefficients when I use the summary command. How can I get the L or skewness coeffecients. I need them to calculate z score Sorry if my...
