Returns predictions and optionally associated quantities (standard errors or confidence intervals) from a fitted segmented model object.

An optional data frame in which to look for variables with which to predict. If omitted, the fitted values are used. |

Basically predict.segmented
builds the right design matrix accounting for breakpoint and passes it
to predict.lm
or predict.glm
depending on the actual model fit object
.
predict.segmented
produces a vector of predictions with possibly associated standard errors or confidence intervals.
See predict.lm
or predict.glm
.
If type="terms"
, 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.
