scen3: Simulated Data - Scenario 3

In adele/FamilyBasedPGMs: Methods for Learning Genetic and Environmental Graphical Models from Family Data

Description

It contains 100 replicates of data simulated according to scenario 3, as described in \insertCiteribeiro2019familyFamilyBasedPGMs.

Usage

scen3

Format

A list with the following elements:

pedigrees

A data.frame representing the pedigrees of all simulated families. It contains the columuns famid, id, dadid, momid, and sex.

fam.nf

A integer vector where the entry i indicates the number of individuals at family i.

phen.nf

A list of size 100 in which each element represents a data.frame with the values of the phenotypes X, Y, and Z for all 900 individuals.

Details

In this scenario, the true DAG in the total, genetic, and environmental components is Z <- X -> Y -> Z and its moral graph is complete. However, data for the total DAG may be unfaithful, since rho_XY|Z is almost zero.

It was simulated pedigrees for 30 families, each with 30 individuals (N = 900).

The same pedigrees were used for simulating 100 replicates of family data for three Gaussian phenotypes, namely X, Y, and Z. No covariates were used in the simulation.
