In mixvlmc: Variable Length Markov Chains with Covariates

Cut off values for VLMC like model

Description

This generic function returns one or more cut off values that are guaranteed to have an effect on the model passed to the function when a simplification procedure is applied (in general a tree pruning operation as provided by prune()).

Usage

cutoff(model, ...)

Arguments

model	a model.
...	additional arguments for the cutoff function implementations

Details

The exact definition of what is a cut off value depends on the model type and is documented in concrete implementation of the function.

Value

a cut off value or a vector of cut off values.

Examples

pc <- powerconsumption[powerconsumption$week == 5, ]
dts <- cut(pc$active_power, breaks = c(0, quantile(pc$active_power, probs = c(0.25, 0.5, 0.75, 1))))
model <- vlmc(dts)
draw(model)
model_cuts <- cutoff(model)
model_2 <- prune(model, model_cuts[2])
draw(model_2)
