comment Determining sample size for AB test with proportion greater than one
Sample sizes and the experimental-group means are obtained by iteratively solving the nonlinear equation (5). There's no easy formula. If you modify the original question with what sort of allocation ratio you're considering, I can modify the answer.

You will need the sd eventually to sure, but I can repeat the calculation for range. Can the treatment "harm"?

Do you know the standard deviation? Do you expect the treatment to alter it?

comment Weird fitted values/residuals plot
@NickCox You're right! I misread the graph and thought that there were no fitted earning below zero, which I interpreted as using logs. I also left out the $\exp()$ around the first expectation in what I wrote.

comment r-squared in quantile regression
@Tim That box doesn't correspond to anything, so it can be ignored. I will try to edit it out later from another machine.

@Tim I don't see anything strange, either in the tex or on the screen.
