Apparent axial dispersion coefficients were found by fitting a three parameter model to tracer-response data.
Apparent ABA affinities (K′d) were calculated from emission ratio plots by fitting a four parameter logistic curve R = R m i n + R m a x − R m i n 1 + ([ A B A ] K ' d ) n or from ΔR/ Δ Rmax plots by fitting a three parameter sigmoidal Hill equation Δ R Δ R m a x = R m a x · [ A B A ] n K d ′ n · [ A B A ] n (Palmer et al., 2006) using the SigmaPlot 10.0 version (Systat, San Jose, CA).
The external loading is described by a four parameter expression, involving the peak overpressure, the loading duration and two parameters which characterize the pulse shape (λ and γ).
It was found that the FCG was controlled by a two parameter driving force in the form of: Δκ= Kmax,totpΔKtot(1−p).
In 2006, Brockmann et al. [16] analyzed more than 460K dollar bills traces concluding that both the jump length and waiting-time distributions in human traveling behavior can be mathematically described by a two parameter continuous time random walk.
Thus LoCoH uses kernels with forms arising directly out of the data, unlike parametric kernels that have a form specified in most cases by a one parameter function (e.g. symmetric bivariate Gaussian centered on the data point with width parameter h), even though the union of these parametric kernels can produce rather irregular surfaces with multiple peaks.
ABA response curves of Col-0 wild type and pyl4ple were fitted by a four parameter logistic curve using data of four single measurements or the combined datasets.
IC50 values for TTX inhibition were estimated by fitting concentration-inhibition data by a four parameter logistic equation using Graphpad Prism 6.0.
Experiments were performed in duplicate and fitted by a four parameter Hill equation R = R 0 + (a · x n c n + x n ) in SigmaPlot 10.0 (Systat, San Jose, CA).
For this study it was assumed that the halothane metabolism could be described by a two parameter Michaelis-Menten (Km and Vmax) liver component.
