NAME

       gbalafit - Fit an asymmetric Laplace density

SYNOPSIS

       gbalafit [options] [files]

DESCRIPTION

       Fit  asymmetric  Laplace  density. Read data from files or from standard input With output
       option '4' prints the log-likelihood as a function of m

       input.

              Options: -O  output type (default 0)

       0      parameters m al ar and negative log-likelihood

       1      the estimated distribution function computed on the provided points

       2      the estimated density function computed on the provided points

       3      parameters m,al,ar their standard errors and correlations

       4      log-likelihood profile

       -m     the mode is not estimated but is set to the value provided

       -x     initial value of m or plot range if output type is '4' (default 0)

       -n     number of plotted points if output type is '4' (default 10)

       -V     verbosity level (default 0)

       0      just the final result

       1      headings and summary table

       2      intermediate steps results

EXAMPLES

       gbalafit -m 1 <file
              estimate al and ar with m=1

       gbalafit -O 4 -x -1,1 <file
              print the log-likelihood on a regular grid from -1 to 1. The grid has 10 points.
