tidy.lm.beta: Tidy a(n) lm.beta object

In broom: Convert Statistical Objects into Tidy Tibbles

Tidy a(n) lm.beta object

Description

Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

Usage

## S3 method for class 'lm.beta'
tidy(x, conf.int = FALSE, conf.level = 0.95, ...)

Arguments

x	An lm.beta object created by lm.beta::lm.beta.
conf.int	Logical indicating whether or not to include a confidence interval in the tidied output. Defaults to FALSE.
conf.level	The confidence level to use for the confidence interval if conf.int = TRUE. Must be strictly greater than 0 and less than 1. Defaults to 0.95, which corresponds to a 95 percent confidence interval.
...	Additional arguments. Not used. Needed to match generic signature only. Cautionary note: Misspelled arguments will be absorbed in ..., where they will be ignored. If the misspelled argument has a default value, the default value will be used. For example, if you pass conf.lvel = 0.9, all computation will proceed using conf.level = 0.95. Two exceptions here are: tidy() methods will warn when supplied an exponentiate argument if it will be ignored. augment() methods will warn when supplied a newdata argument if it will be ignored.

Details

If the linear model is an mlm object (multiple linear model), there is an additional column response.

If you have missing values in your model data, you may need to refit the model with na.action = na.exclude.

Value

A tibble::tibble() with columns:

conf.high	Upper bound on the confidence interval for the estimate.
conf.low	Lower bound on the confidence interval for the estimate.
estimate	The estimated value of the regression term.
p.value	The two-sided p-value associated with the observed statistic.
statistic	The value of a T-statistic to use in a hypothesis that the regression term is non-zero.
std.error	The standard error of the regression term.
term	The name of the regression term.

Examples

# load libraries for models and data
library(lm.beta)

# fit models
mod <- stats::lm(speed ~ ., data = cars)
std <- lm.beta(mod)

# summarize model fit with tidiers
tidy(std, conf.int = TRUE)

# generate data
ctl <- c(4.17, 5.58, 5.18, 6.11, 4.50, 4.61, 5.17, 4.53, 5.33, 5.14)
trt <- c(4.81, 4.17, 4.41, 3.59, 5.87, 3.83, 6.03, 4.89, 4.32, 4.69)
group <- gl(2, 10, 20, labels = c("Ctl", "Trt"))
weight <- c(ctl, trt)

# fit models
mod2 <- lm(weight ~ group)
std2 <- lm.beta(mod2)

# summarize model fit with tidiers
tidy(std2, conf.int = TRUE)
