Proc Rank quintiles but by year

[ksmith133333333]

Hi first time poster, let me know if i need to provide more details.

I am attempting to use proc rank to create quintiles for 4 different variables.

My data is firm-year observations from 2010-2017. I have four variables i need to separately assign quintiles to.

First: Is there a way to have the proc rank consider the year in assigning the quintiles? So it calculates a 2010 set of quintiles and assigns those for the 2010 firm-years, 2011, etc.?

Second: Is there a way to have proc rank ignore missing values in creating the quintiles?

Are your data already sorted by year?   For instance below is dataset sashelp.cars already sorted by ORIGIN (ASIA EUROPE USA).  You can use PROC RANK with a BY statements for all the variables of interest.

proc sort data=sashelp.cars out=have;
  by origin;
run;
proc rank data=have out=want   groups=5 ;
  by origin;
  var    Horsepower          Invoice          Length          MSRP          Weight;
  ranks  Horsepower_quintile Invoice_quintile Length_quintile MSRP_quintile Weight_quintile;
run;

For your dataset, just substitute YEAR for origin and your variables for horsepower--weight.   But remember the quintile variables will be valued at 0 through 4, not 1 through 5.  You may want to run a subsequent data step to add 1 to the quintile variables

It's currently sorted by ein but I can sort it by year. I'll give this a try!
