generate data from a Laplace distr using MTB use sample size of n=30 test the hypothesis H0:median=0 with the t test, T+ test and sign test repeat these tests as the data median is shifted more and more to the right ###################### random 30 c1 ; laplace 0 1 . let c1 = c1 - median(c1) # start with median exactly zero onet c1 ; test 0 . Wtest 0 c1 ; alternative 0 . Stest 0 c1 ; alternative 0 . let c1 = c1 + .05 # raise the median of data by .05 # with copy-paste repeat the last 7 commands # do it 5 to 10 times # make a table of the results: median value (initial, initial+.05,etc) # and the 3 p-values # give an interpretation of the results
