NAME
gblaepfit - Fit a less asymmetric power exponential density
SYNOPSIS
gblaepfit [options] [files]
DESCRIPTION
Fit skewed power exponential density. Read from files or from standard input

Options: -O output type (default 0)
- 0
-
parameter bl br a m and log-likelihood
- 1
-
the estimated distribution function computed on the provided points
- 2
-
the estimated density function computed on the provided points
- -x
-
set initial conditions bl,br,a,m (default 2,2,1,1,0)
- -m
-
the mode is not estimated but is set to the value provided
- -s
-
number of intervals to explore at each iteration (default 10)

-
no optimization
- 1
-
global and local optimization
- -G
-
set global optimization options. Fields are step,tol,iter,eps,msize,algo. Empty field implies default (default .1,1e-2,100,1e-3,1e-5,2)
- -I
-
set local optimization options. Fields are step,tol,iter,eps,msize,algo. Empty field implies default (default .01,1e-3,200,1e-3,1e-5,2)
The optimization parameters are step initial step size of the searching algorithm
- tol
-
line search tolerance iter: maximum number of iterations
- eps
-
gradient tolerance : stopping criteria ||gradient||<eps
- msize
-
simplex max size : stopping criteria ||max edge||<msize
- algo
-
optimization methods: 0 Fletcher-Reeves, 1 Polak-Ribiere, 2 Broyden-Fletcher-Goldfarb-Shanno, 3 Steepest descent, 4 Nelder-Mead simplex, 5 Broyden-Fletcher-Goldfarb-Shanno ver.2 6 Nelder-Mead simplex ver. 2, 7 Nelder-Mead simplex rnd init.
EXAMPLES
- gblaepfit -m 1 <file
