earth
object.
This is the only required argument for summary.earth
.
summary.earth
object.
This is the only required argument for print.summary.earth
.
"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 pmax
"C"
C style expression with zero based indexing
"bf"
basis function format.
"anova"
.
Use "none"
to order the terms as created by the forward.pass.
See format.earth
for a full description.
summary.earth
, the default is getOption("digits")
.
For print.summary.earth
, the default is the $digits
component of object
.
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
fixed.point=FALSE
prints like this (which is more usual in R):(Intercept) 1.5e+01 h(temp-58) 3.1e-01 h(234-ibt) -4.6e-02 ...Matrices with two or fewer rows are never printed with a fixed point.
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.
