  1. PC baseret dataanalyse og simulering Week2 B

  2. SAS Procedurer

  3. Delmængder af data II PROCedurer • Eksempel: • proc print; where koen=‘F’;

  4. Procedurer • proc contents; • proc print;

  5. Procedurer • proc sort; by koen; • proc means; • proc means; by koen;

  6. Procedurer • PROC MEANS; • PROC MEANS options; VAR variables; (PROC MEANS laver sit eget output)

  7. Procedurer • output out=; • output out=B mean=meanx; • output out=mysas.helbred2 sum=sumx N=antal mean=mean;

  8. Procedurer • proc univariate; • proc freq; • proc corr;

  9. Hente et datasæt, som så er default • Libname F_sas ‘f:\dataanalyse\week2\SAS_F’; • Data temp; set F_sas.dat85tot;

  10. Proc freq • proc freq; tables alder koen; • proc freq; tables alder * koen;

  11. Proc tabulate • proc tabulate; class alder koen; table alder, koen;

  12. Proc corr • proc corr; var hojde vaegt; Output: Rho = 0, nulhypotese P-værdi, test af om den sande correlation er 0

  13. Proc corr; !-------------------------------! ! Korrelations-koefficienter ! !--------------!----------------! ! r ! korrelation ! !--------------!----------------! ! 0.00 - 0.19 ! meget svag ! ! 0.20 - 0.39 ! svag ! ! 0.40 - 0.69 ! moderat ! ! 0.70 - 0.89 ! staerk ! ! 0.90 - 1.00 ! meget staerk ! !--------------!----------------!

  14. SAS Put og File

  15. SAS - put og file Eksempel: File print; *File “H:/mysas/udfil”; put navn 1-10 @12 foeddag persnr /;

  16. SAS Grafik

  17. SAS / Graph • proc gplot; • proc gchart; • proc g3d; • proc gslide;

  18. Proc gplot • proc corr; var hojde vaegt; symbol1 V=dot C=red I=RL CI=blue; • Proc gplot; plot hoejde*vaegt=1 hoejde*diastole=1; run;

  19. SAS / Graph - æ, ø og å *goptions devmap=winansi keymap=winansi; proc gslide; title F=swiss "Blåbærgrød"; run;

  20. SAS / Graph - fonte med æ, ø og å SIMULATE CENT**** (flere fonte) SWISS**** (flere fonte) , f.eks. Swiss, Swissl m.fl. ZAPF**** (flere fonte)
