BG/BB models - Work In Progress

Description

Fits BG/BB models on transactional data with static and without covariates. Not yet implemented.

Usage

## S4 method for signature 'clv.data'
bgbb(
  clv.data,
  start.params.model = c(),
  optimx.args = list(),
  verbose = TRUE,
  ...
)

## S4 method for signature 'clv.data.static.covariates'
bgbb(
  clv.data,
  start.params.model = c(),
  optimx.args = list(),
  verbose = TRUE,
  names.cov.life = c(),
  names.cov.trans = c(),
  start.params.life = c(),
  start.params.trans = c(),
  names.cov.constr = c(),
  start.params.constr = c(),
  reg.lambdas = c(),
  ...
)

## S4 method for signature 'clv.data.dynamic.covariates'
bgbb(
  clv.data,
  start.params.model = c(),
  optimx.args = list(),
  verbose = TRUE,
  names.cov.life = c(),
  names.cov.trans = c(),
  start.params.life = c(),
  start.params.trans = c(),
  names.cov.constr = c(),
  start.params.constr = c(),
  reg.lambdas = c(),
  ...
)

Arguments

`clv.data`	The data object on which the model is fitted.
`start.params.model`	Named start parameters containing the optimization start parameters for the model without covariates.
`optimx.args`	Additional arguments to control the optimization which are forwarded to `optimx::optimx`. If multiple optimization methods are specified, only the result of the last method is further processed.
`verbose`	Show details about the running of the function.
`...`	Ignored
`names.cov.life`	Which of the set Lifetime covariates should be used. Missing parameter indicates all covariates shall be used.
`names.cov.trans`	Which of the set Transaction covariates should be used. Missing parameter indicates all covariates shall be used.
`start.params.life`	Named start parameters containing the optimization start parameters for all lifetime covariates.
`start.params.trans`	Named start parameters containing the optimization start parameters for all transaction covariates.
`names.cov.constr`	Which covariates should be forced to use the same parameters for the lifetime and transaction process. The covariates need to be present as both, lifetime and transaction covariates.
`start.params.constr`	Named start parameters containing the optimization start parameters for the constraint covariates.
`reg.lambdas`	Named lambda parameters used for the L2 regularization of the lifetime and the transaction covariate parameters. Lambdas have to be >= 0.
