Here, α 12 represents the effect species 2 has on the population of species 1 and α 21 represents the effect species 1 has on the population of species 2. Coleman November 6, 2006 Abstract Population modeling is a common application of ordinary differential equations and can be studied even the linear case. The VIM is used to obtain solutions of both nonlinear and linear functional equations without discretizing the equations or approximating the operators. Internal Model Estimation (IME) IME estimates the subject's internal forward model of the relationship between the recorded neural activity and cursor movement. The estimate method for arima models uses fmincon from Optimization Toolbox™ to perform maximum likelihood estimation. Essentially, you have to estimate the covariance of adjacent pairs of samples, and then use one of the methods detailed in the paper. generated by Matlab (and others) are actually pseudorandom numbers as they are computed using a deterministic algorithm. The general model and the sub-models with various parameter values are solved using the Variational Iteration Method (VIM), which is a semi analytical method.
