Empirical P Value
...the p value for a stat from the ECDF. That is the index of the first occurrence, on an ordered vector, of a value either greater than or equal to a given value. Ideally I would not have to order the vector beforehand. Currently I use: PValue<-function(stat, ECDF){ ###Get the length of the ECFD L<-length(ECDF) ###Loop through the ECDF until the p value is found for(i in 1:L){ if(ECDF[i]>=stat){ break } } ###Return the 3 values that bracket the p value c((i-1)/L, i/L, (i+1)/L) } Is there a way of doing this that avoids the explicit loop? platform i386-pc...
