Hello everyone,
I am woking on residence data from a university. The full dataset include several residences with rooms and appartments for one to 4 students - a range of single rooms up to quadruple rooms or 4-bedroom appartments.I would want to generate a variabe which looks at the four variables and returns a match.
The four variables include the room number (rmno), the bed id (bed_app - denoting whether it's a double room with letters A and B or a single room with letter S), student id (id), and the id of the requested roommate(s) (req1 - a student can request up to 3 roommates, though I include in the below sample only the variable for the first requested roomate). The match I am looking for is the intersection between the two sets: set 1 of the room number (rmno) and student id (id), and set 2 of the room number and req1.
In the below sample, I looked at only one residence building, which offers either single or double rooms. This is a 10-storey building, of which a floor can consist of rooms numbered from 1 to 16 or 17 depending whether it is an odd or even floor, and rooms on the first three floors are usually limited, preserving the space for the administration. I sorted by the room number, and removed those who did not make a roommate request for the ease of data visualization.
As can be seen, some request were met, while some were not fulfiled by the administration. I am thinking of creating a perfect match (for a double room with two requests which were fulfilled), a partial match (for a triple or quadruple room with one or two fulfilled requests), and unfulfilled match, while keeping a full data set of those who did not make a roommate request.
