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

- b2
binary,logit()=1+p3+b4+p6

- g2
gaussian,identify()=1+b2

- p2
poisson,log()=1+b2

- b3
binary,logit()=1+g1+g2+p2+g3+p3+g4

- g3
gaussian,identify()=1+g1+p3+b4

- p3
poisson,log()=1

- b4
binary,logit()=1+g1+p3+p5

- g4

- p4
