Subject: st: Nonlinear equation
I would like to solve the following nonlinear equation for each individual in my sample.
�
0=X-be-(la/r)*(wespe*exp(0.5*wvari)*norm(ln(X)-ln(wespe)-wvari)/((wvari)^(0.5)))-(X)*norm((ln(X)-ln(wespe))/((wvari)^(0.5))))
�
where "X" is the parameter I want to obtain and "be", "la", "wespe", "wvari" are variables that vary across individuals.
I have tried using the nl command. The problem is that I only have one observation per individual and it could not solve the equation.
�
Thank you very much,
�
