Function Linear-Regression-Minimal-Summaries

Part of:

package cl-mathstats
( linear-regression-minimal-summaries < n > < x > < y > < x2 > < y2 > < xy > )

Calculates the slope and intercept of the regression line. This function
differs from linear-regression-minimal&#39; in that it takes summary statistics:<br> x' and y&#39; are the sums of the independent variable and dependent variables,<br> respectively; x2' and y2&#39; are the sums of the squares of the independent<br> variable and dependent variables, respectively; and xy' is the sum of the
products of the independent and dependent variables.

You should first look at your data with a scatter plot to see if a linear model
is plausible. See the manual for a fuller explanation of linear regression
