lagIndex: Extract list of indices of lag terms

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

Description

Intended for use in conjunction with the estimands functions. For each set of distributed lag terms in the model, find and return the integer indices that would extract the corresponding coefficients from the vector returned by vcoef.

Usage

lagIndex(object, ...)

## S4 method for signature 'dlMod'
lagIndex(object, .fixed = TRUE, ...)

Arguments

object	a fitted model object
.fixed	a logical flag (default .fixed = TRUE) to indicate whether the fixed/unpenalized DL term coefficient indices should be included or not.

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)
vcoef(fit)[lagIndex(fit)[[1]]]
