A superior alternative is to analyze systems that exhibit Bi-logistic growth by using the time-series data to estimate the parameters of a model comprised of the sum of two 3-parameter logistic growth pulses. The Bi-logistic growth model is then

BioPay, a Herndon company that provides secure transaction services, entered into an agreement with BI-LO, a Mauldin, S.C.-based supermarket chain, to use BioPay’s Paycheck Secure® check cashing system at 176 store locations in the southeast. The fingerprint-based system was tested in a 26-store pilot program that began in June. (PRNewswire)

The residuals are useful in determining how well the Bi-logistic model fits the data. If a system is well modeled by the Bi-logistic function, then the residuals will contain only noise, and the residuals will be randomly distributed around zero. The residuals can ... tell a lot about the error structure. The lower part of Figures 3 and 4 show the residuals of the fit on the two time-series data. The residuals are shown as the percent deviation from the estimated value

Digital Auto-Trak Sensitivity tracks each breath so the BiPAP Plus M Series with Bi-Flex and BiPAP Auto M Series with Bi-Flex can cycle between inspiratory and expiratory pressures based on the patient's breathing. It ... automatically adjusts the variable trigger and cycle thresholds to maintain optimum performance in the presence of any leaks, and ensures optimum system response with every breath.
