How do I binning in SAS studio?

You can use the global NUMBIN= option on the PROC HPBIN statement to set the default number of bins for each variable. You can use the INPUT statement to specify which variables to bin. You can override the default number of bins by using the NUMBIN= option on any INPUT statement.

What is quantile binning?

Quantile binning aims to assign the same number of observations to each bin, if the number of observations is evenly divisible by the number of bins. As a result, each bin should have the same number of observations, provided that there are no tied values at the boundaries of the bins.

What is macro and mend in SAS?

macro-name names the macro as it ends a macro definition. Repeating the name of the macro is optional, but it is useful for clarity. If you specify macro-name, the name in the %MEND statement should match the name in the %MACRO statement; otherwise, SAS issues a warning message.

What are SAS macros used for?

SAS has a powerful programming feature called Macros which allows us to avoid repetitive sections of code and to use them again and again when needed. It also helps create dynamic variables within the code that can take different values for different run instances of the same code.

What is a data bin?

Data bins are groups of similar values that we create from a data set. We can then count how often a value from each group occurs to study the distribution of the data set. The key decision to make when creating bins is how many bins to create and what size they should be.

What is equal width binning?

Equal width binning is probably the most popular way of doing discretization. This means that after the binning, all bins have equal width, or represent an equal range of the original variable values, no matter how many cases are in each bin.

What is %let in SAS?

%let creates a macro variable. The value of the macro variable is stored in the macro table. Before the value of the macro variable goes into the symbol table, macro triggers ( & and % are resolved or executed).

What is difference between proc MEANS and proc summary?

Proc SUMMARY and Proc MEANS are essentially the same procedure. Both procedures compute descriptive statistics. The main difference concerns the default type of output they produce. Proc MEANS by default produces printed output in the LISTING window or other open destination whereas Proc SUMMARY does not.
