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.
