💖 GBMODES — the manual, but make it cute 💖

okay bestie, so this is the gbmodes manual page, from the User Commands section, and it's literally about analyzing multimodality in univariate data. no cap. let's get into it 🦋

✨ NAME ✨

gbmodes — analyze multimodality in univariate data 💅

🎀 SYNOPSIS 🎀

gbmodes [options]

that's it. that's the whole vibe. you just run it and it reads stuff from stdin, slay ✨

🌸 DESCRIPTION 🌸

so the whole thing is multimodality analysis via kernel density estimation. it computes the maximal kernel bandwidth h_c(M) for which #(modes in the estimated density)>M. periodt.

the significance of h_c is computed via smoothed bootstrap. no cap, that's the actual method.

it reads data from std. input (standard input, bestie, just pipe it in 🫶).

then it prints the couple h_c p(h_c) and the modal values — you control those modal values with -O, iykyk.

👑 OPTIONS 👑

  • -n — number of equispaced points where the density is computed (default 100). more points, more precision, more main character energy ✨
  • -m — number of modes (default 1)
  • -r — search range for modes; it's a comma separated couple, literally 'data_min,data_max' 📍
  • -s — scale the search range to [min*s+(1-s)*Max,Max*s+(1-s)*min] (default 1)
  • -e — relative tolerance on the h_c value (default 1e-6)
  • -S — significance level (for Hall-York correction) (default .05)
  • -t — number of bootstrap trials used for significance computation (default 1000). a thousand trials, that's dedication fr fr 💪
  • -R — RNG seed for bootstrap trials (default 0)
  • -K — choose the kernel to use: 0 Gaussian or 1 Laplacian (default 0)
  • -v — verbose mode (more verbose if provided 2 times). give it twice and it will NOT stop talking 🗣️
  • -O — output type (default 0)
    • 0 — h_c p(h_c) [modes locations]
    • 1 — h_c [modes locations and heights]
  • -F — specify the input fields separators (default " \t")
  • -h — this help 💖

fr fr, that's the whole page. every flag, every default, every vibe. go forth and analyze that multimodality bestie 🌈⭐

sign-off time 🎀 this was gbmodes 6.2, dated June 2021, from the GBMODES(1) manual. love that for us. byeeee 💖🦋✨
