What are your hypotheses for how the number of rooms registered on a given day to a particular type of guest (TotalRewards, SpecialEvent, VIP, FreeIndependent, Wholesale, Group) affects the number of check-ins?

The quantity of rooms registered on an offered day to a specific kind of guest certainly influences the quantity of registration on that day as can be seen underneath:

Explanation: Total Rewards guest - Total Rewards guests are those guests who have joined the dependability program and win credits on the entirety of their costs which they can later recover for a free stay or sustenance, etc. These sorts of guests are not expansive in number thus they don't put much weight on the number of registrations.

Their number can be normal with no check-ins on a specific day or a few check-ins on another day. So this kind of guest ordinarily doesn't influence the number of check-ins bigly.
