Regarding the weighted average calculation

jacob
Hi,

In weka

 1) i obtained a weighted average of accuracy of classifier 1 = 92.4%
 
2) A weighted average of accuracy of classifier 2 = 93.1%

3) A weighted average of classifier 3 = 92.1%

4) A weighted average of classifier 4 = 87.7

So  i need to calculate the overall weighted average of all classifier. In
simple mathematical terms it will be 92.4 + 93.1 + 92.1 + 87.7/ 4 = 365/4 =
91.325%

So the weighted average of all classifiers is 91.325%. Is this a correct
method to calculate the overall weighted average of classifiers.

Regards
jacob
