I have the split-plot design, factor A-Fertility (whole plot) has three levels and factor B- Plastic (sub-plot) has two levels. Total 3 blocks and 18 sub-plots. I have taken the data (plant yield) at two different times. I wanted to know how to put the cards/data in the correct way while analyzing it.
the data i have right now is in the following form. is this correct or not?
input block fertility plastic time yield;
Second, what would be the proc mixed code for this?
thanks in advance
