select_seasons: Select the number of mortality seasons

In cyclomort: Survival Modeling with a Periodic Hazard Function

Select the number of mortality seasons

Description

Compute a delta AIC table (and, optionally, likelihood ratio tests) for a sequence of models with a different number of seasons

Usage

select_seasons(x, max.season = 4, lrt = FALSE, print = TRUE)

Arguments

x	create_cycloSurv object
max.season	maximum number of seasons to fit
lrt	whether or not to perform and return the complete results of nested likelihood ratio tests
print	boolean parameter; if TRUE the function prints the table out as a side effect of creating the object

Value

a list containing (1) a list of all the fitted objects, and (2) an AIC (and, optionally, LRT) summary table. Also prints both tables by default.

Examples

T.morts1 <- simulate_cycloSurv(1000, period = 1, 
                             meanhazard = 0.3, 
                             peaks = c(0.25, 0.75), 
                             durations = c(0.2, 0.1), 
                             weights = c(0.3, 0.7), 
                             plotme = FALSE)


model_selection = select_seasons(T.morts1, max.season = 4)
summary(model_selection$fits)
