The factors (indicators) were described by a number of quantitative and parametric variables (predictors).
For example, most of the parametric variables in the group called "critical elements of JIT purchasing" are intercorrelated.
If we assume that the average number of years JIT has been in use is four, the percentage of materials purchased according to JIT is 54 percent, the predictor associated with the number of suppliers is equal to 0 (normal number of suppliers), and that all other parametric variables are equal to 1, then the reduction of inventory costs can be expected to be 31.
