In uo-cmor/regtools: Functions for the Analysis of Regression Models

regtools

The goal of regtools is to provide simple tools for the analysis of regression models.

Installation

You can install the released version of regtools from GitHub with:

# install.packages("devtools")
devtools::install_github("uo-cmor/regtools")

Example

This is a basic example which shows you how to solve a common problem:

library(regtools)

df <- data.frame(a = 1:12, b = rep(c("b1", "b2", "b3"), c(4, 5, 3)), c = rep(0:1, c(5, 7)))
model <- lm(a ~ b + c, df)

lincom(model, c(1, 0.5, 0.3, 0.2))
#> $b
#> [1] 6.05
#> 
#> $se
#> [1] 0.7770135

lincom(model, rbind(c(1, 0.5, 0.3, 0.2),
                        c(0.2, 0.3, 0.5, 0.2)))
#> $b
#> [1] 6.05 4.75
#> 
#> $V
#>         [,1]    [,2]
#> [1,] 0.60375 0.58125
#> [2,] 0.58125 0.83375
#> 
#> $F.test
#> $F.test$df.residual
#> [1] 8
#> 
#> $F.test$df
#> [1] 2
#> 
#> $F.test$F.stat
#>          [,1]
#> [1,] 32.41837
#> 
#> $F.test$P
#>              [,1]
#> [1,] 0.0001455319
