ex2.dag.data {abn}

R Documentation

Synthetic validation data set for use with abn library examples

Description

10000 observations simulated from a DAG with 18 variables three sets each from Poisson, Bernoulli and Gaussian distributions.

Usage

ex2.dag.data

Format

A data frame, binary variables are factors. The relevant formulas are given below (note these do not give parameter estimates just the form of the relationships, e.g. logit()=1 means a logit link function and comprises of only an intercept term).

b1

binary,logit()=1+g1+b2+b3+p3+b4+g4+b5

g1

gaussian,identity()=1

p1

poisson,log()=1+g6
