What is the difference between Intck and Intnx functions in SAS?

The INTCK function returns the number of time units between two dates. The INTNX function returns a SAS date that is a specified number of time units away from a specified date. For example, you can use the INTNX function to compute the date that is 308 days in the future from a given date.

What is the Intnx function in SAS?

The INTNX function increments a date, time, or datetime value by intervals such as DAY, WEEK, QTR, and MINUTE, or a custom interval that you define. The INTNX function returns the SAS date value for the beginning date, time, or datetime value of the interval that you specify in the start–from argument.

How do you Intck in PROC SQL?

What are functions in SAS?

SAS has a wide variety of in built functions which help in analysing and processing the data. These functions are used as part of the DATA statements. They take the data variables as arguments and return the result which is stored into another variable.

How are days calculated in SAS?

In general, the difference between two SAS dates in days can most easily be calculated as duration=end_date – start_date. If you want to consider people who (in this case) are admitted and discharged on the same date as having a duration of 1 day, then the formula becomes duration=end_date-start_date+1.

What are SAS procedures?

SAS Procedures exist to carry out all the forms of statistical analysis. A procedure is invoked in a “PROC step” which starts with the keyword PROC, such as: PROC MEANS DATA=CLASS; VAR HEIGHT WEIGHT; The VAR or VARIABLES statement can be used with all procedures to indicate which variables are to be analyzed.

What is the difference between SAS functions and procedures?

FUNCTIONS vs. The fundamental difference between functions and procedures is that a function expects the argument values to supplied across an observation in a SAS data set. Procedures expects one variable value per observation.

How do I use the round function in SAS?

ROUND is the function name; argument is the numeric value or variable you want to have rounded; and rounding-unit is the unit that you want to result to be rounded to (e.g. 10, 100, 0.1, 0.01, 5, etc.) For example, ROUND(34.58, 0.1) tells SAS to round the number 34.58 to the nearest tenth. SAS will return 34.6.
