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 func-
       tion (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
