🎀 GBKREG2D — the manual, but make it slay 🎀

okay bestie, sit down, hydrate, because we're about to talk about gbkreg2d — a User Commands situation from the gbutils fam, and it is lowkey iconic. Kernel non linear regression for bivariate data. yes ma'am. let's get into it 💖

✨ NAME ✨

gbkreg2d — Kernel non linear regression for bivariate data 🦋

✨ SYNOPSIS ✨

gbkreg2d [options]

that's it. that's the whole vibe. no positional args, no drama, just options 🫶

✨ DESCRIPTION ✨

so what's it DOING. 2D kernel estimation of conditional moments, bestie. that's the whole personality. 💅

your data comes in from standard input as triplets — that's (x,y,z) if you're keeping track — and the moments of z get computed on a regular grid in x and y. cute, organized, we love a grid.

the kernel bandwidth? if you don't hand it over yourself with the -H option, it just... sets itself automatically. main character energy, honestly, it knows what it's doing. 🌟 and yes, you can absolutely give different bandwidths for x and y — because they're different girls and they deserve different treatment.

different moments? they land in different data blocks. one block per moment, no mixing, very demure.

and here's the tea ☕: the options -n, -f, -H and -S all accept comma separated values so you can specify different values for the x and y components separately. iykyk. 😌

✨ OPTIONS ✨

  • -n — number of points where the estimation is computed (default 10) ✨
  • -f — fraction of the support for which to print the result (default .9) 🌸
  • -H — set the kernel bandwidth explicitly 💪
  • -S — scale the kernel bandwidth with respect to heuristic 'optimal' 🎯
  • -K — choose the kernel: 0 Epanenchnikov, 1 Rectangular, 2 Silverman type I 3 Silverman type II (default 0) 🧚
  • -O — set the output, comma separated list of m mean, v standard deviation, s skewness and k kurtosis (default m) 📊
  • -D — switch off data de-variation procedure 🚫
  • -v — verbose mode 🗣️
  • -F — specify the input fields separators (default " \t") 🔍
  • -h — this help 🆘
fr fr, notice how -n, -f, -H and -S take comma separated values for x and y. don't forget the comma bestie, she's important. 💀
