showInteraction: Retrieving details of interactions

In jmbh/mgm: Estimating Time-Varying k-Order Mixed Graphical Models

Retrieving details of interactions

Description

Retrieves details of a specified interaction from mgm model objects.

Usage

showInteraction(object, int)

Arguments

object	The output of one of the estimation functions mgm(), tvmgm(), mvar(), tvmvar().
int	An integer vector specifying the interaction. For mVAR models, this vector has length 2. For MGMs the vector can be larger to request details of interaction of order > 2.

Details

Currently the function only returns details of pairwise interactions from output objects of mgm().

Value

variables	Integer vector returning the variables specified via the argument int
type	Character vector returning the type of the specified variables variables
level	Integer vector returning the number of levels of the specified variables variables
parameters	A list of length equal to the order k of the specified interaction. The entries contain the set of parameters obtained from the nodewise regressions on the k variables. Depending on the type of the variables in the interaction, these sets can obtain one or several parameters. For details see ?mgm or Haslbeck & Waldorp (2017).

Examples

## Not run: 


## We fit a pairwise and 3-order MGM to the mixed Autism dataset (?autism_data)

# 1) Fit Pairwise MGM

# Call mgm()
fit_d2 <- mgm(data = autism_data$data,
              type = autism_data$type,
              level = autism_data$lev,
              k = 2) # ad most pairwise interacitons

# Weighted adjacency matrix
fit_d2$pairwise$wadj # for instance, we see there is an interaction 1-2

# 2) Look at details of interaction 1-2
showInteraction(object = fit_d2, 
                int = c(1, 2))
