SAS code for lack-of-fit test

Chrisng2603 — Tue, 10 Nov 2020 00:06:40 GMT

Hi guys, I'm working on a simple lack-of-fit problem and I need an Anova table for some essential quantities like MSE and SSE, here is my code

data Question4; /* Question 4 lack-of-fit */
input TP YP; /* Variables: TP = Temperature(X), YP = Yield of process(Y) */
cards;
50 122
50 118
55 128
55 126
55 125
60 136
60 140
65 142
65 145
70 161
70 165
75 174
run;

proc reg;
model YP = TP / lackfit;
run;

The problem is the code was giving me an empty Anova table with no values of MSE or SSE available, can anyone please help me out with this problem? I also try to input the same data into R to see whether the problem is the same, but R works out really well. However, I was specifically asked to use SAS to solve this problem. Thank you

Try PROC ANOVA

Proc ANOVA data = Question4 ;

Class YP;

Model YP = TP ;

Run;

I run the code and I get what seems to be valid answers. Please put a quit; statement after the run; statement and try it again.
