Often, Exist suggests correlations that are obviously confounded by weekdays. For example, I might cook more the days after I go to the library — but I know that that’s just because I usually go to the library on Thursday and cook more on Friday. It would be very useful to have an overview of correlations that still exist, even when adjusted for weekdays.

Besides weekdays, this process could apply to other attributes, as well, that might be affecting correlations. For example, if you have a correlation between productivity and stress level, perhaps that correlation disappears or changes in strength when controlling for time spent in meetings or your “work from home” tag.
