STEYX

STEYX: Returns the standard error of y-estimates from a simple linear regression.

Summary

STEYX measures the typical residual size around the fitted regression line.

Remarks

  • Requires paired x/y inputs with matching numeric lengths.
  • Requires at least three paired points.
  • Returns #DIV/0! when n < 3 or x-values have zero variance.
  • Pairing and shape mismatches return spreadsheet errors from paired-array validation.
