Dear all

I am trying to run the following code and I am getting a strange error message that I cannot debug. please help me solve it....

ods output parameterestimates=parameterestimates5;
proc nlmixed data=ELISAcalibration4 noad qpoints=15;
num= bottom-top;
den= 1 + exp(slope*(logconc - c50));
expect= top + num/den;
model DO~normal(expect,var);
predict top + num/den out=fitted_values;
ods output ParameterEstimates=parm_est_repl;
ods output CovMatParmEst=cov_parm;
run;

* Data set containing parameter estimates;
data b;
set parm_est_repl;
where parameter in (’top’,’bottom’,’c50’,’slope’);
keep estimate;
run;
* Data set containing the covariance matrix of the parameter estimates;
data covb;
set cov_parm;
where parameter in (’top’,’bottom’,’c50’,’slope’);
keep top bottom c50 slope;
run;
proc sql noprint;
select distinct estimate into: sigma_sq from parm_est_repl where parameter=’var’;
select min(logconc) into: minconc from ELISAcalibration4 where logconc>0;
select max(logconc) into: maxconc from ELISAcalibration4;
run;
quit;

heres the error:

605 * Data set containing parameter estimates;
606 data b;
607 set parm_est_repl;
608 where parameter in (’top’,’bottom’,’c50’,’slope’);

You have invalid (slanted) single quotes in your code, probably from editing outside of SAS with a word processor.

Single quotes must be this character: '
