The goal of lineartestr
is to contrast the linear hypothesis of a model:
Using the DomÃnguez-Lobato test which relies on wild-bootstrap. Also the Ramsey RESET test is implemented.
You can install the released version of lineartestr
from CRAN with:
install.packages("lineartestr")
And the development version from GitHub with:
# install.packages("devtools") devtools::install_github("FedericoGarza/lineartestr")
lm
functionlibrary(lineartestr) x <- 1:100 y <- 1:100 lm_model <- lm(y~x) dl_test <- dominguez_lobato_test(lm_model)
dplyr::glimpse(dl_test$test)
Also lineartestr
can plot the results
plot_dl_test(dl_test)
library(lineartestr) x_p <- 1:1e5 y_p <- 1:1e5 lm_model_p <- lm(y_p~x_p) dl_test_p <- dominguez_lobato_test(lm_model_p, n_cores=7)
dplyr::glimpse(dl_test_p$test)
library(lineartestr) x <- 1:100 + rnorm(100) y <- 1:100 lm_model <- lm(y~x) r_test <- reset_test(lm_model)
dplyr::glimpse(r_test)
An then we can plot the results
plot_reset_test(r_test)
