OPTIMIZATION OF PREDICTOR VARIABLES

摘要

A method and apparatus for optimization of predictor variables. The apparatus includes a value obtaining section to obtain a plurality of answers from an answer database, each answer including an answered value for each variable of a plurality of variables, the plurality of variables answered by each respondent of a plurality of respondents, a cost obtaining section to obtain a cost for answering each of the plurality of variables from a cost database, and a determining section to determine at least one predictor variable from the plurality of variables based on a prediction performance and an answering cost, the at least one predictor variable for predicting at least one remaining variable of the plurality of variables.

1. An apparatus for optimization of predictor variables, comprising:
a value obtaining section to obtain a plurality of answers from an answer database, wherein each answer includes an answered value for each variable of a plurality of variables, the plurality of variables answered by each respondent of a plurality of respondents; a cost obtaining section to obtain a cost for answering each of the plurality of variables from a cost database; and a determining section to determine, using a processor, at least one predictor variable from the plurality of variables based on a prediction performance and an answering cost, the at least one predictor variable for predicting at least one remaining variable of the plurality of variables.
