VT.forest.double {aVirtualTwins} | R Documentation |

## Difft by double random forest

### Description

A reference class to compute twins via double random forests

### Details

`VT.forest.double`

extends `VT.forest`

.

*E(Y|T = 1)* if *T_i = 1* is estimated by OOB predictions from
`model_trt1`

.
*E(Y|T = 0)* if *T_i = 0* is estimated by OOB predictions from
`model_trt0`

.
This is what `computeTwin1()`

does.

Then *E(Y|T = 1)* if *T_i = 0* is estimated by model_trt1.
Then *E(Y|T = 0)* if *T_i = 1* is estimated by model_trt1.
This is what `computeTwin2()`

does.

### Fields

`model_trt1`

a caret/RandomForest/randomForest object for treatment T =
1

`model_trt0`

a caret/RandomForest/randomForest object for treatment T =
0

`...`

field from parent class : `VT.forest`

### Methods

`computeTwin1()`

Compute twin1 with OOB predictions from double forests. See details.

`computeTwin2()`

Compute twin2 by the other part of data in the other forest. See details.
