Dear All: I want to create a scatter plot of grouping data. I have the variable x and y and the grouping variable type (1=group 1, 2=group 2) in the same plot. Also I need to add the fitted regression lines to the same plot. Also, how I can change (or adjust the dots for each type). for example use the square for one type and triangle for the other type. you can use the following data: type x y 1 3 4 1 2 2 1 4 55 1 3 4 1 2 3 2 11 22 1 2 33 2 34 11 2 2 6 2 35 77 2 64 8 1 32 12 1 12 40 2 67 30 2 3 43 2 4 23 1 2 15 1 5 51 1 8 6 2 9 23 2 56 16 1 43 27 2 21 17 1 12 27 1 34 47 1 2 25 2 5 24 2 6 15 2 7 16 1 8 34 1 9 7 2 4 89 1 22 32 2 3 4 1 11 33 1 45 55 2 2 76 1 1 32 2 45 12 1 1 45 2 3 32 1 2 78 1 4 5 1 5 4 1 6 23 2 7 45 1 9 32 2 7 78 2 1 45 2 20 22 Thank you very much abou ========================== AbouEl-Makarim Aboueissa, Ph.D. Associate Professor of Statistics Graduate Program Coordinator Department of Mathematics & Statistics University of Southern Maine 96 Falmouth Street P.O.
