Purpose

Linear regression functions for statistically processed paired data.

Explanation

Function Returns
LRA Linear regression constant term (Y-intercept)
LRB Linear regression coefficient (slope)
  1. These functions calculate the linear regression line Y = LRA + LRB * X from paired (X, Y) data entered using the STAT command.
  2. LRA is the constant term (Y-intercept), representing the value of Y when X is zero.
  3. LRB is the regression coefficient (slope), representing the change in Y per unit change in X.
  4. Paired data must be entered using the STAT command before using these functions.
