**NAME**

nifti_stats - compute NIfTI statistical functions

**SYNOPSIS**

nifti_stats[-q|-d|-1|-z]valueCODE[p1p2p3]

**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.valuecan 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-d0:4:.001 INVGAUSS 1 3 | 1dplot-dx0.001-stdin
