DFBETAs plot data
Description
Prepares the data for dfbetas plot.
Usage
ols_prep_dfbeta_data(d, threshold)
Arguments
d
A tibble or data.frame with dfbetas.
threshold
The threshold for outliers.
Examples
model <- lm(mpg ~ disp + hp + wt + qsec, data = mtcars)
dfb <- dfbetas(model)
n <- nrow(dfb)
threshold <- 2 / sqrt(n)
dbetas <- dfb[, 1]
df_data <- data.frame(obs = seq_len(n), dbetas = dbetas)
