changePoint: Lag coefficient change points

In Biostatistics4SocialImpact/dlm: Distributed Lag Models for Built Environment Applications

Description

For each set of distributed lag terms in the model, finds and returns the (named) integer indices of radii where the corresponding coefficient is significantly different from zero, but the immediately larger radius is not significantly different from zero.

Usage

changePoint(object, ...)

## S4 method for signature 'dlMod'
changePoint(object, ...)

Arguments

object	a fitted model object with viable lagIndex and confint methods
...	additional arguments passed to confint

Value

A list of integer vectors. One list element for each set of DL terms in the model

Examples

data (simdata)

## Setup distance count matrix and corresponding lag distances
X <- as.matrix(simdata[, -(1:3)])
lag <- seq(0.1, 10, length.out = ncol(X))

fit <- dlm(Y ~ Age + Gender + cr(lag, X), data = simdata)
changePoint(fit)
