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.
