tidy.sarlm: Tidying methods for spatially autoregressive models

Description

These methods tidy the coefficients of spatial autoregression models generated by functions of the spatialreg package.

Usage

# S3 method for sarlm
tidy(x, conf.int = FALSE, conf.level = 0.95, ...)

Arguments

x

An object of object returned from spatialreg::lagsarlm() or spatialreg::errorsarlm().

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. Additionally, if you pass newdata = my_tibble to an augment() method that does not accept a newdata argument, it will use the default value for the data argument.

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.

crime_sar <- lagsarlm(CRIME ~ INC + HOVAL, data=COL.OLD,  
  listw=listw, method="eigen")
  
tidy(crime_sar)
tidy(crime_sar, conf.int = TRUE)
