Top: calendar year of study. Middle: month of year. Bottom: day of week. The expectation-variance model has a -value over 0.05 for the entire range of mean specificity values for all three timescales, so the null hypothesis of constant specificity is not rejected. All plots not shown are highly significant (< 0.001) for non-constancy.
