Abstract:
Data showing a rhythm to the naked eye prominently, barely or not at all were described as kinds A, B and C, respectively. Here, we document good agreement between estimates of maxima and minima with eyeballing and with the addition of point and interval estimates of parameters in kind A data. We also construct a chart that provides estimates of uncertainties that can be obtained objectively while they are more difficult to quantify subjectively; again there is agreement. Interval as point estimates of rhythm characteristics and parameter comparisons are useful in charting all kinds of data and become indispensable as we proceed from kind A to kind C data. Illustrations included herein from molecular biology apply equally to all aspects of transdisciplinary science.
