summary.earth: Summary method for earth objects

Description

Summary method for earth objects.

Usage

## S3 method for class 'earth':
summary(object = stop("no 'object' argument"),
        details = FALSE,  style = c("h", "pmax", "max", "C", "bf"),
        decomp = "anova", digits = getOption("digits"), fixed.point=TRUE,
        newdata = NULL, ...)
## S3 method for class 'summary.earth':
print(x = stop("no 'x' argument"),
        details = x$details,
        decomp = x$decomp, digits = x$digits, fixed.point = x$fixed.point,
        newdata = x$newdata, ...)

Arguments

object
An earth object. This is the only required argument for summary.earth.
x
A summary.earth object. This is the only required argument for print.summary.earth.
details
Default is FALSE. Use TRUE to print more information about earth--glm models. But note that the displayed P-values of the GLM
style
Formatting style. One of "h" (default) more compact "pmax" for those who prefer it and for compatibility with old versions of earth "max" is the same as "pmax" but prints max rather than
decomp
Specify how terms are ordered. Default is "anova". Use "none" to order the terms as created by the forward.pass. See format.earth for a full description.
digits
The number of significant digits. For summary.earth, the default is getOption("digits"). For print.summary.earth, the default is the $digits component of object.
fixed.point
Method of printing numbers in matrices. Default is TRUE which prints like this (making it easier to compare coefficients):(Intercept) 15.029 h(temp-58) 0.313 h(234-ibt) -0.046 ... whereas fixe
newdata
Default NULL. Else print R-Squared for the new data (and the returned object will have newrsq and newdata fields). Additionally, if a variance model is present print the interval coverage table for the new data.
...
Extra arguments are passed to format.earth.

Value

  • The value is the same as that returned by earth but with the following extra components.
  • stringsString(s) created by format.earth. For multiple response models, a vector of strings.
  • newrsqOnly if newdata was passed to summary.earth.
  • newdataOnly if newdata was passed to summary.earth.
  • digits
  • details
  • decomp
  • fixed.pointThe corresponding arguments, passed on to print.summary.earth.
