clive,

Change the -ml model- statement to:

ml model lf mlbeta_ll (`lhs'=`rhs', `nocons')  (`dispersion') `if' 
`in', `robust' `svy' 


Example:

. sysuse auto, clear
(1978 Automobile Data)

. qui sum mpg

. gen m2 = mpg/(r(max)+1)

. mlbeta m2 trunk gear, nocons

                                                  Number of obs   
=         74
                                                  Wald chi2(2)    
=      44.06
Log likelihood =  54.205681                       Prob > chi2     
=     0.0000
