The theoretical basis of the fittest method is introduced and the formula for calculating the empirical frequency is introduced.With the statistical test method, the common empirical formula of eight empirical frequencies is selected to compare the pros and cons of the designed value of the P Ⅲtype fittest.The results show that : The result of mathematical expectation formula is too large; the calculation result of Fahrenheit formula, Hessian formula and Маматнов formula is relatively good. The research also shows that the general result of absolute value criterion is better than that of square sum criterion the result of
