Question 1

An analyst is working with datetime values and needs to ensure that they are stored in a SAS dataset as per ISO 8601 standards. Which of the following approaches would correctly convert a datetime value from a character string 'YYYY-MM-DDThh:mm:ss' to a SAS datetime value using the ISO 8601 standards?

Options :

A : Use the `PUT()` function with B8601DT. format on the character string to convert to a SAS datetime value.

B : Use the `INPUT()` function with the E8601DT. informat to convert the character string to a SAS datetime value and apply the B8601DT. format for output.

C : Apply the `INPUT()` function with the ANYDTDTM. informat on the character string, followed by the `FORMAT` statement using the B8601DT. format.

D : Adopt the `DATEPART()` function on the character string first, and then use `TIMEPART()` function with the B8601DT. format to convert to SAS datetime value.

Answer: C

Question 2

A clinical trial dataset is being prepared for statistical analysis and submission to a regulatory authority. Which of the following best describes the purpose of applying the CDISC Analysis Data Model (ADaM) standards to the dataset?

Options :

A : To define the dataset in a way that is specific to the individual clinical trial without consideration for cross-study comparisons.

B : To ensure that the dataset only includes variables that are directly derived from the Case Report Form (CRF).

C : To standardize the dataset structure and variables to facilitate efficient review by regulatory authorities and ensure consistency across studies.

D : To anonymize the clinical trial data to protect patient confidentiality before submission to regulatory agencies.

Which combination of statements and options should you use to modify the marker color, size, and style for each subgroup's reference line, within the context of PROC SGPLOT?

Options :

A : Add the MARKERATTRS= option to the SCATTER statement with appropriate sub-options for color, size, and symbol.

B : Use the REFLINE statement with the STYLEATTRS option and specify sub-options to define colors and markers for each subgroup.

C : Utilize the ATTRID option in the KEYLEGEND statement to match marker attributes with different groups.

D : Apply the GROUP= option with the VLINE statement and customize each reference line using the LINEATTRS= option.

Answer: A
