Predicting Real Growth Using the Yield Curve

The yield curve, which plots the yield of Treasury bonds against their maturity, is one of the most closely watched financial indicators.1 Many market observers carefully track the yield curve’s shape, which is typically upward sloping and somewhat convex. At times, however, it becomes flat or slopes downward (“inverts,” in Wall Street parlance), configurations that many business economists, fi...

Non-linear modeling of kefir grains growth curve

The main objective of this research is non-linear modeling of growth curve during kefir grains batch propagation. For this purpose some laboratory experiments were performed in an RC1 reactor provided data for growth curve construction. Afterwards, we fitted several growth models (Logistic, Gompertz and Richards) and compared their biological parameters. Finally, we established the statisticall...

Estimation of Gompertz growth curve parameters by a non- linear mixed effects model

Abstract Simulated growth data with parameters appropriate for pigs were generated through a 2 step process. First, a linear mixed model was used to produce Gompertz growth curve coefficients for each pig. Then, 30 weekly weights were produced using the coefficients. Simulated pedigree had 3 generations without selection: 10 unrelated grandsires and 200 sires, each with 24 tested offspring. A m...

Model Fit and Interpretation of Non - Linear Latent Growth Curve Models

Predicting Articular Cartilage Behavior with a Non-Linear Microstructural Model

We report here on a non-linear poroelastic model for the mechanical response of collagenous soft tissues such as articular cartilage. The tissue consists of a porous, fibril-reinforced, hyperelastic solid, saturated with an incompressible fluid, and Darcy's law governs solid-fluid interaction. The solid matrix is characterized by the isotropic hyperfoam strain energy function and its permeabili...
