💖 dbcolsregression: linear regression, but make it group-chat 💖

Okay bestie, this is the DBCOLSREGRESSION(1) page from User Contributed Perl Documentation, and it's lowkey iconic. We're doing linear regression between two columns and making it look cute. Let's go. ✨

🌸 NAME 🌸

dbcolsregression — compute linear regression between two columns. That's the whole assignment. 🎀

🦋 SYNOPSIS 🦋

dbcolsregression [-a] column1 column2

🍓 DESCRIPTION 🍓

Compute linear regression over column1 and column2. Outputs slope, intercept, and correlation coefficient. Numbers? Analyzed. Regression? Served. 💅

✨ OPTIONS ✨

  • -a, --include-non-numeric — Compute stats over all records (treat non-numeric records as zero rather than just ignoring them). No skipping records, bestie.
  • -f FORMAT, --format FORMAT — Specify a printf(3)-style format for output statistics. Defaults to "%.5g". Formatting moment.

This module also supports the standard fsdb options:

  • -d — Enable debugging output. Debug era.
  • -i InputSource, --input InputSource — Read from InputSource, typically a file name, or - for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
  • -o OutputDestination, --output OutputDestination — Write to OutputDestination, typically a file name, or - for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
  • --autorun, --noautorun — By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl.
  • --help — Show help. We love a helpful icon.
  • --man — Show full manual. Manual mode unlocked.

🧚 SAMPLE USAGE 🧚

Input:

#fsdb x     y
160 126
180 103
200 82
220 75
240 82
260 40
280 20

Command:

cat DATA/xy.fsdb | dbcolsregression x y | dblistize

Output:

#fsdb -R C slope:d intercept:d confcoeff:d n:q
slope:     -0.79286
intercept: 249.86
confcoeff: -0.95426
n:         7

#  | dbcolsregression x y
#                confidence intervals assume normal distribution and small n.
#  | dblistize
