biglm (version 0.8)

predict.bigglm: Predictions from a biglm/bigglm

Description

Computes fitted means and standard errors at new data values after fitting a model with biglm or bigglm.

Usage

## S3 method for class 'bigglm':
predict(object, newdata, type = c("link", "response"), se.fit = FALSE, make.function = FALSE, ...)
## S3 method for class 'biglm':
predict(object, newdata=NULL,  se.fit = FALSE, make.function = FALSE, ...)

Arguments

object
fitted model
newdata
data frame with variables for new values
type
link is on the linear predictor scale, response is the response
se.fit
Compute standard errors?
make.function
If TRUE return a prediction function, see Details below
...
not used

Value

  • Either a vector of predicted values or a data frame with predicted values and standard errors.

Details

When make.function is TRUE, the return value is either a single function that computes the fitted values or a list of two functions that compute the fitted values and standard errors. The input to these functions is the design matrix, without the intercept column. This allows the relatively time-consuming calls to model.frame() and model.matrix() to be avoided.
