Question

Please provide the SAS code for the question below:

Compute the subject’s age (AGE) as of January 28, 2018 (round to the nearest year)

Using IF-THEN/ELSE statements in the DATA step, create the following categorical variables

WBC_GROUP with 3 levels from the variable WBCCOUNT, as follows:

WBC_GROUP WBCCOUNT

1 3 <= WBCCOUNT < 6

2 6 <= WBCCOUNT <= 10

3 > 10

AGE_GROUP with 3 levels from the variable AGE, as follows:

AGE_GROUP AGE

1 18 <= AGE <=35

2 35 < AGE <= 55

3 Greater than 55

Run Frequency Analysis on the newly created variables, WBC_GROUP and AGE_GROUP in the previous step.

Obtain the CROSS-TABULATION of WBC_GROUP and AGE_GROUP

Obtain the mean of FEV by WBC_GROUP and AGE_GROUP

Sol:

age=floor((intck('month',birthday,today)-(day(today)< day(birthday)))/12);

GE----gretaer thanequal to

LT ---less than

GT--greater than

LE---less than or equal to

if WBCCOUNT GE 3 and WBCCOUNT LT 6 then WBC_GROUP =1;

else if WBCCOUNT GE 6 and WBCCOUNT LE 10 then WBC_GROUP =1;

ELSE if WBCCOUNT GT 10 then WBC_GROUP =3;

if AGE GE 18 and AGE LE 35 then AGE_GROUP=1;

else if AGE GT 35 and AGE LE 55 then AGE_GROUP=2;

ELSE if AGE GT 55 then AGE_GROUP=3;
