The paper presents the method of calculation of distribution loss using neural network MLQP. The precision of this method is much higher than of normal regression analysis method.

The present method extends the traditional multiple regression analysis that is only suitable to normal distribution and complete data to Weibull distribution, extreme distribution and censored data.

The comparisons between hypertensives and their matched controls, the comparisons between groups of high body weight and normal (or low) body weight and the multiple regression analysis were made.
