tidy.systemfit: Tidy a(n) systemfit object

In tidymodels/broom: Convert Statistical Objects into Tidy Tibbles

Tidy a(n) systemfit 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 'systemfit'
tidy(x, conf.int = TRUE, conf.level = 0.95, ...)

Arguments

x	A systemfit object produced by a call to systemfit::systemfit().
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

This tidy method works with any model objects of class systemfit. Default returns a tibble of six columns.

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.
std.error	The standard error of the regression term.
term	The name of the regression term.

Examples

set.seed(27)

# load libraries for models and data
library(systemfit)

# generate data
df <- data.frame(
  X = rnorm(100),
  Y = rnorm(100),
  Z = rnorm(100),
  W = rnorm(100)
)

# fit model
fit <- systemfit(formula = list(Y ~ Z, W ~ X), data = df, method = "SUR")

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