Claim One:
1. A computer-readable recording medium that stores therein a scale-parameter calculating program that causes a computer to implement a method of calculating scale parameters, each of which is for use in normalization of a distribution of values of each of explanatory variables in calculation of inter-explanatory variable distances, to predict a value of a objective variable of an unknown case by extracting one or more known cases similar to the unknown case from known cases based on inter-case distances, the inter-case distances being obtained based on the inter-explanatory distances, each of the inter-explanatory variable distances being a distance between each of the known cases and the unknown case taken for each of explanatory variables, each of the cases including the explanatory variables each expressed by a numerical value and the objective variable expressed by a character string, each of the known cases being a case that has a known objective variable value, the unknown case being a case that has an unknown objective variable value, the scale-parameter calculating program causing the computer to execute: calculating each of the scale parameters for each of the explanatory variables of a union set combined by a known case set of the known cases and an unknown case set of the unknown case; and holding by storing the scale parameters each of which is calculated for each of the explanatory variables in the calculating.
