Abstract:
Computer implemented method stored on a recordable media for revealing necessary and sufficient conditions for data analysis, according to the steps of:i. revealing all if-then rules that relate between the values of one field, selected by a user as a dependent variable, and the other fields in the data set under analysis; ii. for each of said if-then rules discovered, running a Boolean analysis for each value of said dependent variable, said analysis being represented in a two-dimensional table; iii. finding in said two-dimensional table a rule condition having a maximum number of records, where said rule condition holds if and only if said dependent variable value holds; repeating said iii. in regard to records not explained by said discovered rules, to determine rules best explaining chosen results; and iv. checking whether at least one said rule conditions is true, according to a pre-determined threshold, such that conditions meeting said threshold are necessary and sufficient conditions.
