Description
Extract various types of predictions from beta regression models:
either on the scale of responses in (0, 1) or the scale of
the linear predictor.
Usage
## S3 method for class 'betareg':
predict(object, newdata = NULL,
type = c("response", "link"), na.action = na.pass, ...)
Arguments
object |
fitted model object of class "betareg" . |
newdata |
optionally, a data frame in which to look for variables with
which to predict. If omitted, the original observations are used. |
type |
character indicating type of residuals. |
na.action |
function determining what should be done with missing values
in newdata . The default is to predict NA . |

data("GasolineYield", package = "betareg")
gy <- betareg(yield ~ gravity + pressure + temp10 + temp, data = GasolineYield)
