Finding Clocks in Genes: A Bayesian Approach to Estimate Periodicity

Figure 2

Boxplots of period and amplitude estimate for data with different temporal resolutions. Three outliers (one in each rhythmic category by ABSR) are excluded from (a). One arrhythmic profile by ABSR is excluded from (c). Forty-five arrhythmic profiles by ABSR are excluded from (e). Those outliers represent infinitely large period estimates, which imply arrhythmic property.

(a) Period, 4 hr

(b) Amplitude, 4 hr

(c) Period, 2 hr

(d) Amplitude, 2 hr

(e) Period, 1 hr

(f) Amplitude, 1 hr
