Dear All,
I'm new to this area and I need your help!
In order to study the relation between mortality [ 0 (survived) or 1 (died)] that 68 strains produced and the test (I to X), I have applied an univariable logistic regression analysis with proc genmod. So far so good.
proc genmod data=data descend;
class Strain Test;
model Mortality= Strain Test/ dist= binomial link= logit type3 noint aggregate;
lsmeans Strain Test/diff;
run;
Now, I need help with the following. I want to assess the associations between the mortality with the ERIC-PCR results (clusters for each strain, from 1 to 7) and one sequence type (ST) of the strains (binomial variable; 0 = absence and 1=presence).
How I could get the correlation between the mortality and the clusters?
To the association between mortality and the sequence type (ST), I have attempted using the next procedures, and I have achieved the same result, but I am not sure if it is right:
proc genmod data=data descend;
class ST;
model Mortality= ST / dist= binomial link= logit type3 noint aggregate;
lsmeans ST /diff;
run;
proc anova data=data plots(maxpoints=none);
class ST82;
model porcent*=St82;
means ST82/ Bon;
run;
* porcent = number of subjects dead/number of subjects used per strain (in porcent)
proc ttest data=data;
class ST;
var porcent;
run;
I would appreciate some help with the correct syntax for this question...
Thanks in advance!
Ana
Dear pearsoninst,
Thank you very much for your help.
Unfortunately, CORR is considered a syntax error and therefore it is ignored.
Do you have any other suggestions or idea?
Thank you all the same!
If you know, how I could get the correlation between the mortality (binary variable) and the clusters with the Proc REG is also well received.
proc surveyreg data=newdata total=10; cluster Clustervariable; model yvariable=xvariable; run;
and to find only the correlation use CORR Procedure.
Thank you for your suggestion dear pearsoninst!
I don't know the proc surveyreg but I will prove it!
About proc CORR, what would be the best correlation coefficient to analyze my data?
Thank you in advance!
