Hello, I am trying to randomly select rows with unique values in columns 1 and 2. I want to generate multiple subsets to estimate a statistic for each data set. Below is a simplified example.
L1 L2 L3 L4 L5 1 a b 1 2 3 2 a c 4 5 6 3 a d 7 8 9 4 a e 10 11 12 5 a f 13 14 15 6 b c 16 17 18 7 b d 19 20 21 8 b e 22 23 24 9 b f 25 26 27 10 c d 28 29 30 11 c e 31 32 33 12 c f 34 35 36 13 d e 37 38 39 14 d f 40 41 42 15 e f 43 44 45 Could you please give directions to where to start? I have tried eliminating duplicates and finding unique rows but no successful to make it random.
