NAME

       gbnlpanel - Non-linear panel regression

SYNOPSIS

       gbnlpanel [options] <FUN>

DESCRIPTION

       Each row of a block represents a single process realization. Blocks are separated by two white spaces and
       represent   model   variables,   columns   represent   the   time   variable.   Input    is    read    as
       (X1_[r,t],...,Xj_[r,t],...   XN_[r,t]),  where  r  is  the  row,  t the column and j the block. The model
       assumes that

       FUN(X1_[r,t],...,XN_[t,t]) - c_r = e_{r,t}

       with e i.i.d and 'c' arow specific element, which can be fixed (fixed effect) or a normal random variable
       (random effect).
