variable_names: Variable name access

Description

Methods that provide access to the prefixed variable names that the package uses.

prefixed_const_variable: The constant coefficient name is constructed by concatenating the equation prefix with CONST.

prefixed_independent_variables: The names of the independent variables are constructed by concatenating the equation prefix with the column names of the model's data frame.

prefixed_price_variable: The price variable name is constructed by concatenating the equation prefix with the name of the price column.

prefixed_control_variables: The controls of the equation are the independent variables without the price variable. Their names are constructed by concatenating the equation prefix with the name of the price column.

prefixed_control_variables: The variance variable is constructed by concatenating the equation prefix with VARIANCE.

prefixed_quantity_variable: The quantity variable name is constructed by concatenating the equation prefix with the name of the quantity column.

lagged_price_variable: The lagged price variable name is constructed by concatenating LAGGED with the price variable name.

price_differences_variable: The price difference variable name is constructed by concatenating the price variable name with DIFF.
