Hi all, I have four variables (subj, region, eth - all char variables, and score - numeric variable) with a total of 20,000 records.

Below is a syntax used to get count (N), average, standard deviation (SD) and pct for each category (e1 to e5) in the variable of 'eth' BY 'subj' 'region' 'eth'.

AGGREGATE /OUTFILE = 'C:\Data\Sum_A.sav' /BREAK = subj region eth /count = N /avg = MEAN(score) /sd = SD(score) /eth1_frac = FIN(eth,1,1) /eth2_frac = FIN(eth,2,2) /eth3_frac = FIN(eth,3,3) /eth4_frac = FIN(eth,4,4) /eth5_frac = FIN(ethnic,5,5). COMPUTE eth1_N = eth1_frac*count. COMPUTE eth2_N = eth2_frac*count. COMPUTE eth3_N = eth3_frac*count. COMPUTE eth4_N = eth4_frac*count. COMPUTE eth5_N = eth5_frac*count. COMPUTE e1_Pct = eth1_N/count*100. COMPUTE e2_Pct = eth2_N/count*100. COMPUTE e3_Pct = eth3_N/count*100. COMPUTE e4_Pct = eth4_N/count*100. COMPUTE e5_Pct = eth5_N/count*100. Execute.

Below is what Id like to get in addition to the count, mean and SD BY 'subj' 'region' 'eth'. region eth N pct prop 0001 e1 1 2% 0.015384615 0001 e2 5 8% 0.076923077 0001 e3 22 34% 0.338461538 0001 e4 30 46% 0.461538462 0001 e5 7 11% 0.107692308 0001 Total 65 100% 1 But the aggregate function above doesn't seem to work here. Is there a solution using matrix or other functions/syntax? Thank you. Frank
