Dear Statalisters,
I trying to estimate a multinomial model with categorical dependent variable (multi) taking values 1,2 and 3. I would like to constrain some of the coefficients related to the explanatory variables to be zero. After defining the following constraints and estimating mlogit model I get the message below:
constraint define 1 [3] L2debt=0
constraint define 2 [2] debttoas23=0
mlogit multi bktvolkasvu avhelieuribor m2togdp invr3 wint3 capint3 exint3tot3
prcosttot3 glvtot3 rdint1 tplkmyr ika loghenk forown L2profit fixtotot debt
toas23 L2debt logcov, cluster(yrtunnew) constraints(1-2)
redundant or inconsistent constraints
r(412)
I must be doing something wrong when specifying the constraints. I Would really be grateful for help in setting up the constraints.
Thank you in advance.
Best regards,
Laura Vartia
