Predict method for segmented model fits
Returns predictions and optionally associated quantities (standard errors or confidence intervals) from a fitted segmented model object.
a fitted segmented model coming from
An optional data frame in which to look for variables with which to predict. If omitted, the fitted values are used.
further arguments passed to
predict.segmented builds the right design matrix accounting for breakpoint and passes it
predict.glm depending on the actual model fit
predict.segmented produces a vector of predictions with possibly associated standard errors or confidence intervals.
predict.segmented returns predictions for each component of the segmented term.
Namely if ‘my.x’ is the segmented variable, predictions for ‘my.x’, ‘U1.my.x’ and ‘psi1.my.x’ are returned. These are
meaningless individually, however their sum provides the predictions for the segmented term.
