A method for multi-way heteroscedastic analysis is presented

which detailedly discusses the heteroscedastic analysis of one

two and multiple factors

in the condition of the same coefficient of variation in all states.It can test whether the multiple populations have a certain kind of different means

and estimate their parameters.With small sample

it can test the results of simulation or digital design and analyze the influence of each factor in the results.And then

it can point out which factors have been simulated correctly and which haven’t.Furthermore

this method can correct the results of simulation or digital design according to the experimental data.
