GBALAFIT

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.
