lr: Linear Regression with g2 inverse

In sasLM: 'SAS' Linear Model

Linear Regression with g2 inverse

Description

Coefficients are calculated with the g2 inverse. The output is similar to summary(lm()).

Usage

  lr(Formula, Data, eps=1e-8)

Arguments

Formula	a conventional formula for a linear model
Data	a data.frame to be analyzed
eps	A value less than this is considered zero.

Details

It uses G2SWEEP to get the g2 inverse. The result is similar to summary(lm()) without options.

Value

The result is comparable to that of SAS PROC REG.

Estimate	point estimate of parameters, coefficients
Std. Error	standard error of the point estimate
t value	value for the t distribution
Pr(>|t|)	probability of a larger absolute t value from the t distribution with the residual degrees of freedom
