Good afternoon, I have a question on generating simple randomization data. Thanks for any suggestions.
Two normal distribution N(0,1) and N(1,1) A: I want to generate 20 data, 10 from N(0,1) and 10 from (1,1). each observation's indicator (either is from N(0,1) or N(1,1) ) is randomized. I need use the frist 10 data from the generated 20 dataset. (it is not necessary 5 from N(0,1) and 5 from N(1,1) for these 10 data, since the indicator for the 20 data is randomized) . For example, the 10 data's indicator could be 0 0 0 1 0 1 1 0 0 0 (0 means the observation is from N(0,1) and 1 indicates the observations is from N(1,1)) B: still the same 20 data generate data above. I want the indictor is forced to be balanced in the first 10 data. That is, if I use the first 10 data, 5 are from N(0,1) and 5 are from (1,1). For example, the 10 data's indicator could be 0 1 1 0 0 1 0 1 1 0 How can I generate the 20 data . Sorry it is a little confusing. I want to generate the data not the indicator. The dataset I want to generated in A is not balanced for the frist 10, in B it is balanced in the first 10. I want to use the same dataset, how can I use to method to randomize it.
