How to conduct a EFA on MPLUS with ordinal data

 

In the previous Example we use a simple syntax from MPLUS to produce basic descriptives. In the following example we introduce new commands in mplus: EFA and PLOT.

This example, is only descriptive for showing the commands, no special remarks are made on how to interpret the loadings, the scree test, nor the ouput. The main thing is just for showing the command lines [in the future, we or I, should produce an special topic on how to deal with the question of ‘how many factors’ and ‘how to report a factor analisys’].

The syntax to use is:

title: EFA on ordinal data;
data: file = C:\EXAMPLE01.txt;
! if we still have the same previous data from the example,
! everything should work
variable: names =
year
NUNICO
con1 con2 con3
con4 con5 con6
con7 con8 con9
con10 con11  var1;
     CATEGORICAL are
con1 con2 con3
con4 con5 con6
con7 con8 con9
con10 con11;

     USEVARIABLES =

con1 con2 con3
con4 con5 con6
con7 con8 con9
con10 con11 ;     

     missing = all (-99);
ANALYSIS: TYPE = EFA 1 4;
PLOT:    
   TYPE IS 
  PLOT3;  
OUTPUT: MODINDICES;

This example, require the use of the previous data. Here is the video tutorial,  the notes, the syntax, and the mplus output.
