I have the following SAS codes below,trying to compute an F statistics. What divisor should I use? .I'm testing Ho Vs Ha.
Estimate 'Ho:2M1+2M2+2M3-3M4-3M5' Y 2 2 2 -3 -3/DIVISOR= ? ;
How to determine a linear trend in the response variable as the class variable increases?
How to determine quadratic trend in the reponse variable as the class variable increases?
How to determine if the assumption of linear/quadratic trend in the response variable to the class variable is appropriate by simultaneously testing the cubic and quadratic trends to be zero by testing;
Ho: -1M1 + 2M2 + 0 M3 - 2M4 + 1M5 = 0, 1M1 - 4M2 + 6 M3 - 4 M4 + 1M5 = 0 versus
Ha not Ho).
