check.RestrAndConst {elect}

Checking the definition of RestrAndConst in elect

Description

Function to check the definition of RestrAndConst in the elect call.

Usage

check.RestrAndConst(x, RestrAndConst, PRINT = FALSE)

Arguments

x

Fitted msm model

RestrAndConst

Vector which indexes the independent parameters in model\$opt\$par w.r.t. to the model parameters

PRINT

TRUE for printing the comparison

Details

Function to help defining the parameter constraints in the elect call\ when the constraint option is used in msm.

Value

TRUE when RestrAndConst is well-defined, FALSE otherwise.

Examples

# Fit model with constraints:
Q     <- rbind(c(0,0.01,0.01), c(0,0,0.01), c(0,0,0))
model <- msm(state~age, subject = id, data = electData,
             center = FALSE, qmatrix = Q, deathexact = TRUE,
             fixedpars = c(7,8), covariates = ~age+x)
RestrAndConst <- c(1:6,0,0,7)
check.RestrAndConst(model, RestrAndConst, PRINT= TRUE)

# Usage: elect(x = model,..., RestrAndConst = RestrAndConst)
