Need help!! My SAS code won't work

caroline_rg — Sun, 11 Feb 2024 16:34:23 GMT

Hi!

I am a MSc student and I am having difficulty running my SAS code. I am looking at mammary gland data from pigs. Each variable was measured once. The project has a completely randomized design.

I am trying to run ANOVAs and tukeys tests on the data. My descriptive stats will run, but thats as far as it will go.

Here is my code so far:

Data GLANDES_TRUIE;
	infile "/home/u62306126/sasuser.v94/LYS3/glande_stats.csv" dlm="," firstobs=2;
	input TRUIE TRAIT ADN_PAR_SEC ARN_PAR_SEC BW NBR_TET
      PCT_GRAS_SEC PCT_MS PCT_PROT_SEC PDS_EXTRA PDS_PAR PDS_PAR_TET  
      RATIO_ARN_ADN RATIO_EXTRA_PAR RATIO_PROT_ADN RATIO_PROT_ARN
      TOT_ADN_PAR TOT_ADN_TET TOT_ARN_PAR TOT_ARN_TET TOT_GRAS_PAR TOT_PROT_PAR;
Run;

PROC CONTENTS; run;
data GLANDES_TRUIE;
  set lecture_GLANDES;
  if TRAIT=1 then TRT="CONTROL";
  if TRAIT=2 then TRT="SOYBEAN";
  if TRAIT=3 then TRT="CASEIN";
  if TRAIT=4 then TRT="LYSINE";
  trt_TRUIE=compress(SUBSTR(TRT,1,3)||"_"||truie);
proc print;
run;

/* descriptive stats */
proc means data=GLANDES_TRUIE maxdec=2;
  class TRAIT;
  var ADN_PAR_SEC ARN_PAR_SEC BW NBR_TET
      PCT_GRAS_SEC PCT_MS PCT_PROT_SEC PDS_EXTRA PDS_PAR PDS_PAR_TET  
      RATIO_ARN_ADN RATIO_EXTRA_PAR RATIO_PROT_ADN RATIO_PROT_ARN
      TOT_ADN_PAR TOT_ADN_TET TOT_ARN_PAR TOT_ARN_TET TOT_GRAS_PAR TOT_PROT_PAR;
run;

/* descriptive stats separate tables for each variable */
proc sort data=GLANDES_TRUIE;
  by variable trait trt truie;
run;

proc means data=GLANDES_TRUIE maxdec=2;
  class trt;
  var GLANDE;
  BY variable;
run;

/* each variable analyzed separately */
proc sort data=GLANDES_TRUIE;
  BY variable;
proc mixed data=GLANDES_TRUIE;
  class TRAIT truie;
  model GLANDE=TRAIT/ outp=outpred;
  repeated / group=TRAIT;
  ods output tests3=tests;
  lsmeans TRAIT / cl;
  ods output lsmeans=lsm;
  BY variable;
run;

/* non-parametric analysis */
proc npar1way DATA=GLANDES_TRUIE wilcoxon;
  class TRT;
  var GLANDE;                                                                                                     
  by variable;     
ods output WilcoxonTest=WilcoxonTest (rename=nValue1=Wilcoxon);
run;

proc print data=WilcoxonTest noobs; 
  where name1="PT2_WIL";
  var variable;
  var Wilcoxon /  style(Column)=[background=colorFMT.];
  format Wilcoxon 6.4; 
run;

Thank you!!

Caroline

Hi, when you say "that's as far as it will go", what happens after that? If you look at the log, do you see ERROR messages? One of the most important parts of learning SAS learning how to read the log. You always want to review your log before you look at any results. If you the log has ERRORs or WARNINGs, you need to fix them, before you trust your results.

If you look at your log and can't figure out what it means, please paste the log into a post here, and people can help you. One thing I noticed if you have a lot of code like:

proc sort data=GLANDES_TRUIE;
  by variable trait trt truie;    * <-- you do not have a variable named VARIABLE ;
run;

The second line is a BY statement, commonly used in SAS for processing data in groups, or in this case for sorting data into groups. A BY statement expects the list of words after the word BY to be the names of variables that exist in the input data. With this code, it will expect the data to have a variable named VARIABLE. I don't think that exists in your data, which should trigger an error message. Perhaps try:

proc sort data=GLANDES_TRUIE;
  by trait trt truie;  * <-- removed the word VARIABLE ;
run;

proc means data=GLANDES_TRUIE maxdec=2;
  class trt;
  var GLANDE;
  BY trait trt truie;  * <-- replaced the word VARIABLE with the list of variables you sorted by above;
run;

Note also above that the CLASS statement and BY statement have similar purposes in PROC MEANS. While they could be used together, it's unlikely this will give you the result you want. It would probably be better for you too think about the groups you want to have PROC MEANS output for, and then use either a CLASS statement or BY statement to define those groups.

Please be specific and tell us what EXACT part of your code doesn't work. Also please tell us what about this doesn't work — are there errors in the log? do you get output but its the wrong output?

If you get errors in the log, please show us the ENTIRE log for this PROC, copy the log as text and paste it into the window that appears when you click on the </> icon.

If the code produces output but its the wrong output, show us the output and explain what you think is wrong.

The data set lecture_glandes does not exist. You have to fix this in order for the rest of your code to work properly.

Another lesson in SAS is that you rarely (never) want to write an entire program and run it all. Because a problem in step #2 will make everything after it useless. It's much easier to write the first DATA step, run it, and debug it. Then write the next step, run it, and debug it. After you have all the steps working, it's a good idea to start a new SAS session and run them all at once. But while you're writing code, running each step one-at-a-time as you are writing is usually more helpful than running the whole program.

Thank you! I've fixed that. The error message:

ERROR 73-322: Expecting an =.
 73               PCT_GRAS_SEC PCT_MS PCT_PROT_SEC PDS_EXTRA PDS_PAR PDS_PAR_TET
 74               RATIO_ARN_ADN RATIO_EXTRA_PAR RATIO_PROT_ADN RATIO_PROT_ARN
 75               TOT_ADN_PAR TOT_ADN_TET TOT_ARN_PAR TOT_ARN_TET TOT_GRAS_PAR TOT_PROT_PAR=TRAIT/outp=outpred;

Is relating to this section of code:

ERROR 73-322: Expecting an =.
 73               PCT_GRAS_SEC PCT_MS PCT_PROT_SEC PDS_EXTRA PDS_PAR PDS_PAR_TET

 75               TOT_ADN_PAR TOT_ADN_TET TOT_ARN_PAR TOT_ARN_TET TOT_GRAS_PAR TOT_PROT_PAR=TRAIT/outp=outpred;

I am confused as to why it says it is expecting a "=". There is an equal sign between the variables and trait

Re: Need help!! My SAS code won't work

According to GLIMMIX documentation: https://documentation.sas.com/doc/en/statcdc/14.2/statug/statug_glimmix_syntax15.htm

the syntax is:

MODEL response <(response-options)> = <fixed-effects> </ model-options>;

e.g.,

model y=x / ALPHA=0.07;

And, if I see it correctly in your log, you don't have it in this form.

Hi Bart,
Are you able to explain how it is not in this form? All of my variables (the "y") are equal to the trait (the "x"). I have changed the code to have "/alpha=0.05", but get the same error message. I'm not sure why SAS isn't recognizing my "=" between the y and x

Because you don't have one.

 92         model ADN_PAR_SEC ARN_PAR_SEC BW NBR_TET
 93               PCT_GRAS_SEC PCT_MS PCT_PROT_SEC PDS_EXTRA PDS_PAR PDS_PAR_TET
 94               RATIO_ARN_ADN RATIO_EXTRA_PAR RATIO_PROT_ADN RATIO_PROT_ARN
 95               TOT_ADN_PAR TOT_ADN_TET TOT_ARN_PAR TOT_ARN_TET TOT_GRAS_PAR TOT_PROT_PAR=TRAIT;

Which of those variables is the DEPENDENT variable (the one that the model is going to predict the value for)? Place that before the = and then list the INEDEPENDENT variables (the ones used as the basis for the predictions) after the =.

In PROC GLIMMIX (as shown by @yabwon by quoting the SAS documentation), you can have only a single Y variable. You cannot have multiple Y variables. So, assuming the Y variable is ADN_PAR_SEC the command you want is

model ADN_PAR_SEC = BW NBR_TET ... ;

and then you include BW and NBR_TET and all the rest of the X-variables (also called independent variables) in the model statement.

NOTE: Your code actually began with

 model ADN_PAR_SEC ARN_PAR_SEC BW NBR_TET

and the first two variables are identical, and you cannot enter a variable into the model statement more than once.
