  1. Sigmoidal Response (knnl558.sas)

  2. Programming Example: knnl565.sas Y = completion of a programming task (1 = yes, 0 = no) X2 = amount of programming experience (months) n = 25

  3. Programming Example: input data programming; infile‘H:\My Documents\Stat 512\CH14TA01.DAT'; input experience complete; procprintdata=programming; run;

  4. Programming Example: Scatterplot procsortdata=programming; by experience; title1'scatterplot with smoothing'; symbol1v=square i=sm60 c=blue; procgplotdata=programming; plot complete*experience; run;

  5. Programming Example: Scatterplot (cont)

  6. Programming Experience: Logistic Regression procgenmoddata=programming descending; model complete = experience/dist=binomial link=logittype1 aggregate; run;

  7. Programming Experience: Logistic Regression (cont) PROC GENMOD is modeling the probability that complete='1'.

  8. Programming Experience: Logistic Regression (Cont)

  9. Programming Example: Fitted Curve symbol1v=square i=nonec=blue; symbol2v=nonei=join c=blue; procgplotdata=fit; plot complete*experience pred*experience/overlay; run;

  10. Programming Example: Hypothesis test
