predict.risk_mod {riskscores}

Predict Method for Risk Model Fits

Description

Obtains predictions from risk score models.

Usage

## S3 method for class 'risk_mod'
predict(object, newx = NULL, type = c("link", "response", "score"), ...)

Arguments

object

An object of class "risk_mod", usually a result of a call to risk_mod().

newx

Optional matrix of new values for X for which predictions are to be made. If ommited, the fitted values are used.

type

The type of prediction required. The default ("link") is on the scale of the predictors (i.e. log-odds); the "response" type is on the scale of the response variable (i.e. risk probabilities); the "score" type returns the risk score calculated from the integer model.

...

Additional arguments.

Value

Numeric vector of predicted values.

Examples

y <- breastcancer[[1]]
X <- as.matrix(breastcancer[,2:ncol(breastcancer)])
mod <- risk_mod(X, y, lambda0 = 0.01)
predict(mod, type = "link")[1]
predict(mod, type = "response")[1]
predict(mod, type = "score")[1]
