std_beta: Retrieve std. beta coefficients and ci of lm and mixed models

Description

Returns the standardized beta coefficients and confidence intervals of a fitted linear (mixed) models, i.e. fit must either be of class lm or lmerMod (lme4-package).

Usage

std_beta(fit, include.ci = FALSE)

Arguments

Value

A vector with standardiized beta coefficients of the fitted linear model, or a data frame with standardized confidence intervals, if include.ci = TRUE.

Examples

Run this code

# fit linear model
fit <- lm(airquality$Ozone ~ airquality$Wind + airquality$Temp + airquality$Solar.R)
# print std. beta coefficients
std_beta(fit)

# print std. beta coefficients and ci
std_beta(fit, include.ci = TRUE)
