Claim One:
1. An EDR direction estimating method for estimating EDR directions in a single index model related to a large number of variables, comprising the steps of inputting a data file to be analyzed; receiving data to be analyzed, the data composed of sets of response variables and explanatory variables, standardizing the explanatory variables, and outputting data composed of sets of standardized explanatory variables and response variables; receiving the data composed of the sets of standardized explanatory variables and response variables, dividing the data into two slices with reference to a predetermined threshold for the response variables, calculating the mean vector of the standardized explanatory variables on a slice basis, and outputting the mean vector for each slice; receiving the mean vector for each slice, calculating the difference between the two mean vectors to determine an EDR direction, and outputting the EDR direction data to data conversion means; and converting the EDR direction data to a unit vector, and outputting the unit vector as an estimated value for the EDR direction.
