R: Predict method for a speedglm object

predict.speedglm {speedglm} | R Documentation

## Predict method for a speedglm object

### Description

`summary` The method is currently under construction but some functionalities are available.

### Usage

    ## S3 method for class 'speedglm'
    predict(object, newdata, type = c("link", "response"),
                               na.action = na.pass, ...)

### Arguments

`object` | an object of class 'speedlgm'.
`newdata` | An optional data frame with new data or the original data.
`type` | Type of prediction.
`na.action` | function determining what should be done with missing values in `newdata`.
`...` | further optional arguments

### Details

If `newdata` is omitted prediction are based on the data used for the fit only if argument `fitted` was previously set to `TRUE` in the speedglm object. Currently the method does not work for function `shglm`.

### Value

`pred` | a vector of predictions.

### Examples

    set.seed(10)
    y <- rgamma(20,1.5,1)
    x <-round( matrix(rnorm(20*2),20,2),digits=3)
    colnames(x) <-c("s1","s2")
    da <- data.frame(y,x)
    mod <- speedglm(y~s1+s2, data=da, family=Gamma(log), fitted=TRUE)
    predict(mod)
