anova problem

samsun — Mon, 02 Dec 2024 08:32:55 GMT

I use SAS 9.4 to do anova analysis, and fallow the instruction, the result only shows anova but didn't show tukey. Are there any problem with software.

Did you means this ?

proc glm data=sashelp.heart;
class bp_status;
model weight=bp_status/solution;
lsmeans bp_status/diff adjust=tukey lines;
quit;

Likely there are problems with your code. Don't keep us in the dark, show us your code!

here is the results

only anova but no tukey.

I don't know if the problem is software(9.4) or program.

thank you so much

From now on, please provide code as text, in the code box (little running man icon), and not as screen captures.

This code works properly for me, I see the Tukey information underneath the output where you see

This is what I see

Please read carefully, I said the code should be in a code box, that's the window that appears when you click on the "little running man" icon.

I don't know why the Tukey analyses appears for me and doesn't appear for you.

Does the Tukey analysis appear as a graph, like this:

samsun — Mon, 02 Dec 2024 13:55:53 GMT

the results were shown as before, there is not the same with yours, that is why I ask for someone help here.

Re: anova problem

PaigeMiller — Mon, 02 Dec 2024 13:58:12 GMT

So I can't explain why I get the Tukey and you don't, using the exact same code. If no one else here can figure it out, I suggest you contact SAS Tech Support at 1-800-727-0025 (in the USA). If you are outside the USA, you will have to look on the SAS web site to find the proper phone number.

Hi PaigeMiller,
Thank you for your answer.

Which version of sas are you using ?

Try to run the following code to check it.

%put &sysvlong.;

Try to run the following code :

ods graphics;
proc anova data=Clover;
class Strain;
model Nitrogen = Strain;
means Strain / tukey;
quit;

the SAS vision is 9.4

the following example is from SAS instruction.

the results shown in my computer were only anova but no tukey.

That' why I am looking for someone's help.

proc anova data=Clover;
class Strain;
model Nitrogen = Strain;
means Strain / tukey;
run;

Someone have shown me the result was no problem.

but I did not see the same result on my computer.

I'll try you code later.

Thank you.
