# Base SAS (Geometric Means and Related)

[ Edited ]

I've seen similar posts but I am trying to determine if there is a simpler method for this:

1. Create log10 transformed values of x

2. Process through PROC MEANS to obtain mean, sd, median, min max

3. Raise each of the quantities in (2) to 10**(mean), etc. to get "mean", "SD", "min", and "max" values

4. Calculate dispersion factors

-All quantities based on output from Means procedure in step 2

dfplus=(10**mean)+(10**(mean+sd)-10**(mean));

dfminus=(10**mean)-(10**(mean)-10**(mean-sd));

Since I need to calculate grand mean, sd, min, max, dfplus, and dfminus by anaysis category, is there a way I can reduce the number of steps?

## Re: Factor analysis using maximum likelihood estimation

I don't understand what your question has to do with the title of this post, "Factor analysis using maximum likelihood estimation."

What are you trying to accomplish? What variables are you using in the factor analysis?

Here could get you many statistical estimators .

``````data class;
set sashelp.class;
log_height=log(height);
run;
proc univariate data=class outtable=want noprint;
var log_height;
run;``````
