## Function Linear-Regression-Brief

(

**linear-regression-brief** < dv > < iv > )

Calculates the main statistics of a linear regression: the slope and

intercept of the line, the coefficient of determination, also known as r-square,

the standard error of the slope, and the p-value for the regression. This

function takes two equal-length sequences of raw data. Note that the dependent

variable, as always, comes first in the argument list.

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

statistics.
