Overview

lm.hw4 is a package to fit and analyze linear regression model, including following functions.

lm_fit() estimates the parameters of the linear regression models.
lm_summary() summarizes the properties of the fitted model.
lm_anova() computes analysis of variance (or deviance) tables for fitted model objects.

Installation

install.packages("devtools")
library(devtools)
install_github("leyaozh/lm.hw4", build_vignettes = TRUE, force = TRUE)

Usage

library(lm.hw4)

# use dataset mtcats as an example
attach(mtcars)
x = cbind(hp, wt, hp * wt)
y = mpg

z = lm_fit(x, y, add.intercept = TRUE, method = "qr")
z
z.summary = lm_summary(z, correlation = TRUE)
z.summary
z.anova = lm_anova(z)
