summary.ldbglm {dbstats}R Documentation

Summarizing local distance-based generalized linear model fits

Description

summary method for class "ldbglm".

Usage

  ## S3 method for class 'ldbglm'
summary(object,dispersion = NULL,...)

Arguments

object

an object of class ldbglm. Result of ldbglm.

dispersion

the dispersion parameter for the family used. Either a single numerical value or NULL (the default)

...

arguments passed to or from other methods to the low level.

Value

A list of class summary.ldgblm containing the following components:

nobs

number of observations.

trace.hat

Trace of smoother matrix.

call

the matched call.

family

the family object used.

deviance

measure of discrepancy or goodness of fitt. Proportional to twice the difference between the maximum log likelihood achievable and that achieved by the model under investigation.

df.residual

the residual degrees of freedom.

null.deviance

the deviance for the null model.

df.null

the residual degrees of freedom for the null model.

iter

number of Fisher Scoring (dblm) iterations.

deviance.resid

the deviance residuals for each observation: sign(y-mu)*sqrt(di).

pears.resid

the raw residual scaled by the estimated standard deviation of y.

dispersion

the dispersion is taken as 1 for the binomial and Poisson families, and otherwise estimated by the residual Chisquared statistic (calculated from cases with non-zero weights) divided by the residual degrees of freedom.

kind.kernel

smoothing kernel function.

method.h

method used to decide the optimal bandwidth.

h.opt

the optimal bandwidth h used in the fitting proces (if method.h!=user.h).

crit.value

value of criterion defined in method.h.
