Dear Drs. Muthén! I have a data set collected through stratified sampling. The number of samples in the data set is 400 and each sample has values of 11 variables, including its strata and weight. I divided the data set into 4 groups by a variable (a0), which is neither strata nor weight variables. I wanted to compare the descriptive statistics and the regression estimation result of each group. So, I got a result with the following command syntax; TITLE: HG_feul poverty_test1 DATA: FILE IS hg_fp_test1.txt ; FORMAT IS free ; LISTWISE IS OFF; VARIABLE: NAMES ARE id strata pw HB RF TW W_HL WIN BOT ef a0; USEVARIABLES ARE strata pw HB RF TW W_HL WIN BOT ef a0; MISSING are all(-999); STRATIFICATION IS strata; WEIGHT IS pw; ANALYSIS: TYPE = COMPLEX ; iteration = 2000; MODEL: ef on HB RF TW W_HL WIN BOT; OUTPUT: stdyx; SAMPSTAT; I'm wondering if this syntax is right, even though the result looks correct, I guess. |

Your input doesn't have anything related to a0. You can create 3 dummy indicators out of a0 and add those to the regression. |

Oh, I already split the data set into 4 data sets and I used the same syntax with 4 data sets respectively. Was this way wrong? But, thank you for your advice. I'll try it! |
