st: Re: RE: Fw: regarding stata MLE
Dear Nick,
I am now facing a problem in getting results for ml estimation in
stata.
the program that I have writen in a lf file is:-
program define myprog
args lnf theta1 theta2
quietly replace
'lnf'= -.5*ln(2*_pi)-.5*ln('theta2')-.5*(($ML_y1-'theta1')^2)/'theta2'
end
the statistical details that I have used to form the program is
1. the dependent vriable is normally distributed
the log likelihood is
]
then in the command window I typed
. ml model lf myprog (reg: name of dependent variable = name of independent
variables)
. ml maximize
now i am getting the eror 198 invalid name
please suggest me what i am doing wrong
Best,
suddhasil

This is already programmed for you as -regress-.

I've just begun with the maximum likelihood with Stata.
Can you please help me in this regard. My estimation equation is a linear
one with normal distribution.
Y = constant + ax1 +b x2, where y is the dependent variable, a, b are the
coefficient and x1, x2 are the independent variables.
Can you please help me in providing a programme that will run for the
equation.
