我使用nlogit5运行如下命令时

SAMPLE ; All $

SETPANEL; Group = id ; Pds = ti $

ORDERED; Lhs = hsat

; Rhs = one,hhninc,hhkids,educ ; Partial Effects $

总是提示如下错误信息：

Error 805: Initial iterations cannot improve function.Status=3

在网上找到如下解决方法：

If you get a warning message of “Error: 806: Line search does not improve fn. Exit iterations. Status=3” or “Error: 805: Initial iterations cannot improve function. Status=3”, you may change the optimization algorithm or increase the maximum number of iterations (e.g., Maxit=1000$).

于是把命令改为：

SAMPLE ; All $

SETPANEL; Group = id ; Pds = ti $

ORDERED; Lhs = hsat

; Rhs = one,hhninc,hhkids,educ ; Partial Effects ; Maxit = 1000 $

但依然提示上述错误。请高手们给个解决的办法吧。谢谢！数据文件见附件！
