Betreff: st: non linear regression

Dear Everyone,

 my dependent variable continuously range from -2 to 2. so, i must use
logistic function to limit my estimated  value of y.
  I would like to run nonlinear(logistic) function . I read the manual in
the stata version 8 and think  i should use -nl- command . i use
nl log4 y x1 x2 x3 x4 x5 x6 , initial(b0 -2 b1 4)

but when i run the coefficient is come out only four parameters of beta of
logistic function, not the estimated coefficient for each of my independent
variables.

 I would like to see the nonlinear relationship between my y and my xs.
Could anybody please give me some advice regarding command in stata.

Bests regard,
somsupa
A Phd student.
