Hi, here the same sequence in SPSS and in PSPP. There are 2 differences in result. * SPSS 22. * N=170. COUNT norm1=SW1 TO SW5 (7). FREQUENCIES VARIABLES=norm1 /ORDER=ANALYSIS. * value 0 cases 134; values <> 0 cases 36. MISSING VALUES SW1 TO SW5 (7). COUNT mis1=SW1 TO SW5 (7). FREQUENCIES VARIABLES=mis1 /ORDER=ANALYSIS. * value 0 cases 134; values <> 0 cases 36. COMPUTE mis2=NMISS(SW1 TO SW5). FREQUENCIES VARIABLES=mis2 /ORDER=ANALYSIS. * value 0 cases 123; values <> 0 cases 47. RECODE SW1 TO SW5 (7=-7). COUNT mis3=SW1 TO SW5 (7). FREQUENCIES VARIABLES=mis3 /ORDER=ANALYSIS. * value 0 cases 170; values <> 0 cases 0. MISSING VALUES SW1 TO SW5 (-7). COUNT mis4=SW1 TO SW5 (-7). FREQUENCIES VARIABLES=mis4 /ORDER=ANALYSIS. * value 0 cases 134; values <> 0 cases 36. ============================================== * psppire.exe 0.8.4-g0011a5. * N=170. COUNT norm1=SW1 TO SW5 (7).
