lognormal_normal2log

PURPOSE

convert characteristics of log-normal random variable X

SYNOPSIS

function [mu_log,sigma_log] = lognormal_normal2log(mu,sigma,convention)

DESCRIPTION

 convert characteristics of log-normal random variable  X 
 into mean and std dev of random variable Y = log(X)
 characteristics are given by:
  convention 'arithmetic': mean and std dev
  convention 'geometric': geometric mean and spread = geom.mean * (geom.std.dev - 1 )

CROSS-REFERENCE INFORMATION

This function calls:

default commandstring = default(varname1,defaultvalue1,varname2,defaultvalue2,...)
