Abstract	An alternative to the Satterswaite-Welch degrees of freedom (df) is developed in this paper based on unbiased estimating equations. The method enables us to evaluate the impact of sample variation due... to using estimated df instead of the true df by computer intensive method. It is shown by simulation that the alternative df is close to the Welch df and the method developed could be also used for evaluating the impact of sample variation due to using estimated df in the Welch test.show more
