💖 NIFTI_STATS 💖

okay bestie, this is the manual for nifti_stats — it's a User Command, it lives in section 1 of the manual, and it is genuinely the moment for anyone who's ever needed a statistical distribution to just show up on the command line. 🎀

✨ NAME ✨

nifti_stats — compute NIfTI statistical functions 🧮💅

🦋 SYNOPSIS 🦋

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

like... that's it. that's the whole invocation. she's compact. 👑

🌸 DESCRIPTION 🌸

so nifti_stats supports a whole lil squad of distributions — normal, uniform, logistic, chi, etc. — and it calculates density or the cummulative distribution function (and honestly, many more). Values get printed to stdout, and you can absolutely pipe them into other tools. it's giving pipeline main character energy. 🔥

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

not me listing every single one of these because they ALL matter, bestie. no skips. 💯

Following CODE are distributional parameters, as needed.

Results are written to stdout, 1 number per output line. yes. one. per. line. clean. 🧼✨

🍓 EXAMPLE 🍓

Piping output into the AFNI program 1dplot:

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

obsessed. this is the whole vibe: you compute, you pipe, you plot. 🫶📈
