nifti_stats

PURPOSE ^

Conversion among various statistics

SYNOPSIS ^

function varargout = nifti_stats(varargin)

DESCRIPTION ^

 Conversion among various statistics
 FORMAT P = nifti_stats(VAL,CODE,OPT,PARAM)
   CODE can be one of
     'CORREL'      'TTEST'       'FTEST'       'ZSCORE'
     'CHISQ'       'BETA'        'BINOM'       'GAMMA'
     'POISSON'     'NORMAL'      'FTEST_NONC'  'CHISQ_NONC'
     'LOGISTIC'    'LAPLACE'     'UNIFORM'     'TTEST_NONC'
     'WEIBULL'     'CHI'         'INVGAUSS'    'EXTVAL'
     'PVAL'
   With only one input argument, CODE defaults to 'ZSCORE'

   OPT can be one of
     '-p' ==> output P = Prob(statistic < VAL).
     '-q' ==> output is 1-p.
     '-d' ==> output is probability density.
     '-1' ==> output is X such that Prob(statistic < x) = VAL.
     '-z' ==> output is Z such that Normal cdf(Z) = p(VAL).
     '-h' ==> output is Z such that 1/2-Normal cdf(Z) = p(VAL).
   With less than three input arguments, OPT defaults to '-p'.

   PARAM are up to three distribution parameters.
   These default to zero if unspecified.

   P is an array with the same dimensions as VAL.
