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 |
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. |
