These functions are used to enable the use of the corresponding link function between the survival and longitudinal models in a joint model. Note that the exact implementation of the link function is model specific, see vignette("Statistical Specifications", package = "jmpost") for more details.

Usage

linkNone()

linkTTG(prior, model = PromiseLongitudinalModel(), ...)

linkDSLD(prior, model = PromiseLongitudinalModel(), ...)

linkIdentity(prior, model = PromiseLongitudinalModel(), ...)

linkGrowth(prior, model = PromiseLongitudinalModel(), ...)

Arguments

prior

(Prior)
A Prior object.

model

(LongitudinalModel)
A LongitudinalModel object.

...

Not used.

Functions

  • linkNone(): No link (fit the survival and longitudinal models independently)

  • linkTTG(): Time to growth link

  • linkDSLD(): Derivative of the SLD over time link

  • linkIdentity(): Current SLD value link

  • linkGrowth(): Growth Parameter link
