Create Transition Models Table

Source: R/trans_models_t.R
trans_models_t.Rd

Creates a trans_models_t table for storing transition model metadata and serialized model objects. This function creates an empty table with proper structure for storing fitted models.

Usage

as_trans_models_t(x)

# S3 method for class 'trans_models_t'
print(x, nrow = 10, ...)

Arguments

x

A list or data.frame coercible to a data.table

nrow

see data.table::print.data.table

...

passed to data.table::print.data.table

Value

A data.table of class "trans_models_t" with columns:

  • id_trans: Foreign key to trans_meta_t

  • model_family: Model family (e.g., "rf", "glm", "bayesian")

  • model_params: Map of model (hyper) parameters

  • goodness_of_fit: Map of various measures of fit (e.g., ROC AUC, RMSE)

  • fit_call: Character string of the original fit function call for reproducibility

  • model_obj_part: BLOB of serialized model object for validation

  • model_obj_full: BLOB of serialized model object for extrapolation

Methods (by generic)

  • print(trans_models_t): Print a trans_models_t object, passing params to data.table print
