I need all your help on this. I have the next part of code:............e1=x1-mean(x1)e2=x2-mean(x2)n1=length(x1)n2=length(x2N=(n1 + n2)nu2=sum( c(  ( x1 -mean(x1) )^2 , ( x2-mean(x2) )^2  ) )/Nss=c(e1,e2) b3= N*sum(ss^4)/ (sum( ss^2)^2)............what do lines 6-8 (mathematical notation)?Also the, what means part?............for(j in 1:B){ ss11=sample(x1, n1, replace=TRUE) ss12=sample(x2, n2, replace=TRUE) ............}............????I would appreciate you could help on my inquiry, and I am awaiting for your soon answer Thx in advance, Lusk
