Please make your question clear, some expert may give you some advice.

Do you have 3 block or 6 blocks in total? Are the data as in Design 1 or 2 in attachment?

If design 1:

proc glm;

title 'Design 1';

model resp1 - resp28 = / nouni ss3;

repeated a 2, b 7, c 2 / nom;

run;

If design 2:

proc glm;

title 'Design 1';

class a;

model resp1 - resp14 = a / nouni ss3;

repeated b 7, c 2 / nom;

run;

Thanks for your answers.

Dear Jos

The design is more and less similar to option1.

I have to mention that I had 3 blocks but the experiment repeated in 2 locations.(3 blocks in each location totaly making 6 blocks).

The designs:

location 2 * block 3 * factor a 2 (main plot) * factor b 7 (sub plot) * factor c 2 (sub-sub plot)

and response variables were measured.

Could you please let me know of your comment?

Thank you so much for your advice

Dear Alexandra

Thank you for your comment.

Could you please make also a comment on the model for analysis in SAS?

Any tip is appreciated

Then I think it is Design 2:

Your Blocks are the "subjects" or units of observation. You have 3 per location (factor a).

SAS program (fabricated data as example; see also attachment):

(be sure to check if the sequence corresponds to the 7 x 2 design

data a;

input a block $ resp1-resp14;
