timing: Timing Information for INLAvaan Models

Description

Extract wall-clock timings for individual computation stages of a fitted INLAvaan model.

Usage

timing(object, ...)
# S4 method for INLAvaan
timing(object, what = "total", ...)

Value

A named numeric vector (class c("timing.INLAvaan", "numeric")) of elapsed times in seconds. Printing formats short durations as seconds, longer ones as minutes or hours.

Arguments

object

An object of class INLAvaan.

...

Currently unused.

what

Character vector of timing segment names to return, or "all" to return every segment. Defaults to "total". Available segments (depending on model options): "init", "optim", "vb", "loglik", "marginals", "norta", "sampling", "covariances", "definedpars", "deltapars", "test", "total".

Examples

# \donttest{
HS.model <- "
  visual  =~ x1 + x2 + x3
  textual =~ x4 + x5 + x6
  speed   =~ x7 + x8 + x9
"
utils::data("HolzingerSwineford1939", package = "lavaan")
fit <- acfa(HS.model, HolzingerSwineford1939, std.lv = TRUE, nsamp = 100,
            test = "none", verbose = FALSE)

# Total elapsed time
timing(fit)

# All stages
timing(fit, what = "all")

# Specific stages
timing(fit, what = c("optim", "marginals"))
# }
