Stop statement causes SAS to prevent processing this knowledge step at once and resume the process statement when the tip of current knowledge step.

45. What’s the distinction between mistreatment drop = knowledge set possibility in knowledge statement and set statement?

Ans:

If you are doesn’t need to method bound variables and you do not need them to seem within the new knowledge set, then specify drop = knowledge set possibility within the set statement.Whereas If need to method bound variables and don’t need them to seem within the new knowledge set, then specify drop = knowledge set possibility within the knowledge statement.

SUM performs the total of non-missing arguments whereas “+” operator returns a missing value if any of the arguments are missing.

49. What are the variations between PROC means that and PROC SUMMARY?

Ans:

PROC means that produces subgroup statistics only if a BY statement is employed and therefore the computer file has been antecedently sorted (using PROC SORT) by the BY variables.PROC outline mechanically produces statistics for all subgroups, providing you with all the data in one run that you simply would get by repeatedly sorting an information set by the variables that outline every subgroup and running PROC means that. PROC outline doesn’t turn out any info in your output. therefore you may have to be compelled to use the OUTPUT statement to form a replacement knowledge SET and use PROC PRINT to envision the computed statistics.

Ans:

• Value of month would be thirteen.
• No. of observations would be one.

55. However, do dates add SAS data?

Ans:

• Data is central to each knowledge set. In SAS, knowledge is offered in tabular type wherever variables occupy the column area and observations occupy the row area.
• SAS treats numbers as numeric knowledge and everything else falls below character knowledge. Thus SAS has 2 knowledge sorts numeric and character.
• Apart from these, dates in SAS are drawn in a very special way compared to different languages.

Ans:

58. What’s the distinction between do whereas and do until?

Ans:

An important distinction between the DO till and DO whereas statements is that the DO whereas expression is evaluated at the highest of the DO loop. If the expression is false the primary time it’s evaluated, then the DO loop ne’er executes.

59. However, does one specify the quantity of iterations and specific conditions among one do loop?

Ans:

This unvarying DO statement allows you to execute the DO loop till total is bigger than or adequate 20000 or till the DO loop executes ten times, whichever happens 1st.

62. Think about the subsequent SAS Program:

Ans:

63. What’s interleaving in SAS?

Ans:

Interleaving combines individual, sorted SAS knowledge sets into one sorted SAS knowledge set. for every observation, the subsequent figure shows the worth of the variable by that the information sets area unit sorted. You interleave knowledge sets employing a SET statement beside a BY statement.In the following example, the information sets are area units sorted by the variable Year. we will be kind and so be a part of the datasets on Year with the below code.

64. What’s PDV?

Ans:
