NAME

       nifti_stats - compute NIfTI statistical functions

SYNOPSIS

       nifti_stats [-q|-d|-1|-z] value CODE [p1 p2 p3]

DESCRIPTION

       nifti_stats  supports  several  distributions  (normal,  uniform, logistic, chi, etc.) and
       calculates density or cummulative  distribution  function  (and  many  more).  Values  are
       printed to stdout and can be piped to other tools.

       value can be a single number or in the form bot:top:step.
              default ==> output p = Prob(statistic < val).

       -q     ==> output is 1-p.

       -d     ==> output is 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).

       Allowable CODEs:

       CORREL,  TTEST,  FTEST,  ZSCORE,  CHISQ,  BETA, BINOM, GAMMA, POISSON, NORMAL, FTEST_NONC,
       CHISQ_NONC, LOGISTIC, LAPLACE, UNIFORM, TTEST_NONC, WEIBULL, CHI, INVGAUSS, EXTVAL,  PVAL,
       LOGPVAL and LOG10PVAL

              Following CODE are distributional parameters, as needed.

       Results are written to stdout, 1 number per output line.

EXAMPLE

       Piping output into AFNI program 1dplot:

              nifti_stats -d 0:4:.001 INVGAUSS 1 3 | 1dplot -dx 0.001 -stdin
