Summarizing Kernel Semi parametric Model Fits
Description
summary method for an object of class "kspm"
Usage
## S3 method for class 'kspm'
summary(object, kernel.test = "all",
global.test = FALSE, ...)
Arguments
object |
an object of class "kspm", usually, a result of a call to |
kernel.test |
vector of characters indicating for which kernel a test should be performed. Default is |
global.test |
logical, if |
... |
further arguments passed to or from other methods. |
Details
the description of the model, including coefficients for the linear part and if asked for, test(s) of variance components associated with kernel part.
Value
Computes and returns the followimg summary statistics of the fitted kernel semi parametric model given in object
residuals |
residuals |
coefficients |
a |
sigma |
the square root of the estimated variance of the random error |
edf |
effective degrees of freedom |
r.squared |
|
adj.r.squared |
the above |
score.test |
a |
global.p.value |
p value from the score test for the global model. |
sample.size |
sample size (all: global sample size, inc: complete data sample size). |
