SASInstitute Clinical Trials Programming Using SAS 9.4 A00-282 Prüfungsfragen mit Lösungen

Frage #1

What is the primary purpose of programming validation?

A. Justify the means used to accomplish the outcome of a program and ensure its accurate representation of the original data.
B. Efficiently ensure any logic errors are discovered early in the programming process.
C. Ensure that the output from both the original program and the validation program match.
D. Document all specifications pertaining to programmed output and ensure all were reviewed during the programming process.

Frage #2

The programmer runs a validation program of the SDTM DM domain which produces the following in the log in SAS:

What does the validator need to check?

A. The sort order of both the production and validation datasets.
B. The formatted data values for SEX and AGE.
C. The labels of both the production and validation datasets.
D. The internal data values for SEX and AGE.

Frage #3

In a Statistical Analysis Plan (SAP) the following statement is written:
To test the association between the pain intensity reported by the patient and the treatment the patient has been administered, a Cochran-Mantel-Haenszel test will be performed adjusting for the country of the patient's investigational site.
The following variables and levels are used:
- Pain intensity (PAIN): "No pain", "Mild pain", "Moderate pain", "Severe pain", "Most severe pain"
- Treatment group (TREAT): "Placebo", "Drug A", "Drug B"
- Country (COUNTRY): Eight different values.
The following program is written to perform this analysis:
proc freq data=pain;
by COUNTRY;
tables PAIN * TREAT / cmh;
run;
This code does not produce the analysis requested by the SAP.
What is wrong with this code?

A. The option CMH should be on the PROC FREQ statement instead of on the TABLES statement.
B. The variable COUNTRY should be on the TABLES statement instead of the BY statement.
C. The variable PAIN should be on the BY statement along with the variable COUNTRY.
D. The variables PAIN and TREAT should be on the BY statement, and the variable COUNTRY should be on the TABLES statement.

Frage #4

The first six (6) records from the LABS data set are shown below:

The following SAS program is written to reshape this data set and place it in a new data set named LBTR.
proc transpose data=labs out=lbtr(rename = (col1 = value));
by subjid sampldat;
var Calcium Glucose Hemoglobin;
run;
Which of the following DATA steps produces a data set that is equivalent to the LBTR data set created by the PROC TRANSPOSE step above?

A. data lbtr2(drop = i calcium glucose hemoglobin);
set labs;
array orig[3] calcium glucose hemoglobin;
array testcds[3] $ 10 _temporary_ ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
do i = 1 to 3;
value = orig[i];
_name_ = testcds[i];
end;
output;
run;
B. data lbtr2(drop = i calcium glucose hemoglobin);
set labs;
array orig[3] calcium glucose hemoglobin;
array testcds[3] $ 10 ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
do i = 1 to 3;
value = orig[i];
_name_ = testcds[i];
output;
end;
run;
C. data lbtr2(drop = i calcium glucose hemoglobin);
set labs;
array orig[3] calcium glucose hemoglobin;
array testcds[3] $ 10 ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
do i = 1 to 3;
value = orig[i];
_name_ = testcds[i];
end;
output;
run;
D. data lbtr2(drop = i calcium glucose hemoglobin);
set labs;
array orig[3] calcium glucose hemoglobin;
array testcds[3] $ 10 _temporary_ ("CALCIUM" "GLUCOSE" "HEMOGLOBIN");
do i = 1 to 3;
value = orig[i];
_name_ = testcds[i];
output;
end;
run;
