My model for the -mvprobit- command is: mvprobit (SM1=)(SM2= affiloui1 filialOUparticipOUI1 apeIAA1 fboisson1 fcerealalimanim1 ffruitsleg1 fviande1 fAUTRES1 lnadha1 lnrpr311)(SM3= MCAautres1 MCAnon1 MCAgros1 MCApart1 MCAgdist1 lnpmonde1 lnpunion1 CAregmoins501 ef501 lnrpr311) and this shows me the results for the model (omitted) and for coefficients /atrho21 -.9462691 /atrho31 -.1293586 /atrho32 -.3407803 rho21 -.7380893 rho31 -.1286418 rho32 -.3281738 I am interested in changing any of the /atrho value to 1. Is it possible in Stata 11.2? Saqlain RAZA PhD Student ======================= -mvprobit- is on SSC. Your question is not clear, but it appears that you wish to constrain some of the cross-equation correlations to specific values. Linear constraints on /atrho values (equivalently, correlations) can be imposed using -constraint-. Stephen ------------------ Professor Stephen P.
