Update method for the ModelPseudo model class. This is a method to update the model class slots (estimates, parameters, variables and etc.), when the new data (e.g. new observations of responses) are available. This method is mostly used to obtain new modal estimates for pseudo model parameters.

Description

Update method for the ModelPseudo model class. This is a method to update the model class slots (estimates, parameters, variables and etc.), when the new data (e.g. new observations of responses) are available. This method is mostly used to obtain new modal estimates for pseudo model parameters.

Usage

## S4 method for signature 'ModelPseudo'
update(object, data, ...)

Arguments

object	(ModelPseudo) the model to update.
data	(Data) all currently available of data.
...	not used.

Value

the new ModelPseudo class object.

Examples

# Update the 'LogisticIndepBeta' model with new data.
empty_data <- Data(doseGrid = seq(25, 300, 25))

my_model_lib <- LogisticIndepBeta(
  binDLE = c(1.05, 1.8),
  DLEweights = c(3, 3),
  DLEdose = c(25, 300),
  data = empty_data
)

# Then, we have some new observations data.
data <- Data(
  x = c(25, 50, 50, 75, 100, 100, 225, 300),
  y = c(0, 0, 0, 0, 1, 1, 1, 1),
  ID = 1:8,
  cohort = c(1L, 2L, 2L, 3L, 4L, 4L, 5L, 6L),
  doseGrid = empty_data@doseGrid
)

# Update the model to get new estimates.
new_model_lib <- update(object = my_model_lib, data = data)

# Update the 'Effloglog' model with new data.
empty_data_dual <- DataDual(doseGrid = seq(25, 300, 25), placebo = FALSE)

my_model_eff <- Effloglog(
  eff = c(1.223, 2.513),
  eff_dose = c(25, 300),
  nu = c(a = 1, b = 0.025),
  data = empty_data_dual,
  const = 0
)

# Data with new observations data.
my_data_dual <- DataDual(
  x = c(25, 50, 50, 75, 100, 100, 225, 300),
  y = c(0, 0, 0, 0, 1, 1, 1, 1),
  w = c(0.31, 0.42, 0.59, 0.45, 0.6, 0.7, 0.6, 0.52),
  ID = 1:8,
  cohort = c(1L, 2L, 2L, 3L, 4L, 4L, 5L, 6L),
  doseGrid = empty_data_dual@doseGrid
)

# Update the model to get new estimates.
new_model_eff <- update(object = my_model_eff, data = my_data_dual)
