Description Usage Arguments Value Examples

Predictive accuracy estimates (MSE) across trees for linear or poisson regression model.

1	compute.mse(response, predictions)

`response`	A vector of actual response of outcome variable.
`predictions`	A vector of predicted response for the same outcome variable.

MSE estimates

# The MSE should be 2.5. Off by 2 half the time, off by 1 the other half
response <- matrix(c(rep(0,100), rep(10,100)))
predictions <-
    matrix(nrow=20, ncol = 3,
           data = c(rep(1,100), rep(8,100), rep(1,100), rep(8,100),
                    rep(1,100), rep(8,100)))
compute.mse(response, predictions)
