lr: Linear Regression with g2 inverse

In sasLM: 'SAS' Linear Model

Linear Regression with g2 inverse

Description

Coefficients calculated with g2 inverse. 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	Less than this value is considered as zero.

Details

It uses G2SWEEP to get 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 t distribution
Pr(>|t|)	probability of larger than absolute t value from t distribution with residual's degree of freedom
