We intended to perform a meta-analysis if data were clinically homogeneous by calculating summary estimates with nonlinear models using either random-effects or fixed-effects approaches.
The ventilation incident is detected by monitoring the torque losses, estimated with a nonlinear observer.
New aspects of the method are the combination of nonlinear Gauss Seidel smoothing on the finest grid with linear coarse-grid corrections, and local damping in the initial stages of the computation, to keep the solution stable; the damping needed is estimated with the nonlinear smoother.
Finally, the posterior distributions of parameters and the posterior model probabilities were estimated with the nonlinear regression approach [feed-forward neural network (FFNN) regression models] developed by Blum and Francois (2010) and implemented in the R package abc.
The parameter of demographic expansion τ was estimated with a generalized nonlinear least squares approach and approximate confidence intervals were obtained with 1000 parametric bootstrap replicates.
Moreover, ventilatory complexity must be estimated with a combination of nonlinear techniques, since respiratory time series are often very noisy and highly nonstationary, compared with cardiovascular signals [ 38, 43].
The reaction kinetic parameters, rate coefficients and stoichiometric coefficients, as well as the mass transfer coefficient are estimated by nonlinear estimation with the developed novel reaction kinetic model.
