How to conduct a hypothesis test : Ho:|E(X)|=|E(Y)|<->H1:otherwise NOT R question
Dear R-list,
I am sorry for my shortage of stat knowlege. I want know how to conduct a
hypothesis test : Ho:|E(X)|=|E(Y)|<->H1:otherwise.
Actually, in my study, X and Y is two observations of bias,
where bias=u^hat-u, u is a parameter I concerned. Given X=(u^hat_xi - u) and
Y=(u^hat_yi - u), I want to know which bias is smaller, or the absolute
expection of which is smaller. Due to limit of sample size, I think we
cannot make a conclusion by comparing the absolute mean value of each
sample. So I turn to a means of hypothesis testing as I post in the title.
Now my strategy is us...
