summary.pnt: Summary method for S3 class "pnt" objects.

In psychNET: Psychometric Networks for Intensive Longitudinal Data

Description

Generic function that is used in order to summarize information from "pnt" class objects.

Usage

## S3 method for class 'pnt'
summary(object, ...)

Arguments

object	: An object obtained by the psychNET function.
...	: Not used in this version of the package.

Details

This a generic function that summarize the information of the networks obtained after a time series model has been fitted to data. Since the main function psychNET is a wrapper of several models the summary methods of each method can also be used (if available) by typing summary(object$fit) where object is an object obtained by the psychNET function.

Value

The function summary.pnt returns a list with the following components:

contemporaneous

: When estimates of the covariance matrix (contemporaneous network) are available then contemporaneous is a list with two components named local and global that describe the contemporaneous network locally and globally. For global description of the network, transitivity, reciprocity, distance, density, and diameter are returned in a one column matrix. At the local (nodes) level the function calculates node transitivity, the degree centrality, step-1 and -2 node expected influence, betweeness centrality and closeness centrality.

temporal

A list with two components named local and global that describe the temporal network locally and globally. At the global graph level the same descriptives as in the contemporaneous network are returned for each lag of the VAR model. At the local level, node transitivity, in and out degree centrality, step -1 and -2 expected influence centralities, betweeness, out and in closeness centralities are returned to the user.
