The Estimate Method

Input:
The estimate() method takes exactly the same arguments as its parent class:
specification, dataset, outcome_attribute, index, procedure, data_objects, and estimate_config. The default value for outcome_attribute is ``unit_price''.

Algorithm:
The method applies the filter_attribute (if given) in the same way as the run() method. It then calls the parent method estimate() passing all arguments and the possible modified index.

Output:
The method returns results of estimate() method of RegressionModel (see Section 24.4.4).
