  • Aggregation of Random Parameters Ornstein

    In this paper we consider the aggregation scheme introduced in the paper of Granger (1980), where it was shown that aggregation of random parameter AR(1) processes can produce long memory...

  • [08040185] Log

    This allows us to prove that the probability distributions associated with these processes possess some very simple aggregation properties accross time scal Such a control of the process properties at different time scales, allows us to address the problem of parameter estimation...

  • Model validation and model

    Model validation and model-based data analysis Using gPROMS' state-of-the-art parameter estimation facilities A gPROMS ® advanced process model is constructed from first-principles equations describing the physical and chemical phenomena occurring in the system...

  • Parameter Estimation

    Parameter estimation plays a critical role in accurately describing system behavior through mathematical models such as statistical probability distribution functions, parametric dynamic models, and data-based Simulink ® models Improving the accuracy of statistical models can involve estimating:...

  • Optimal Parameter Estimation of Conceptually

    Two classes of conceptual-stochastic models, ARMA and Shot Noise, are taken under consideration as equivalent to a conceptual system transforming the effective rainfall into runoff Using these models, the possible benefits of data aggregation with regards to parameter estimation are investigated by means of a simulation study...

  • On the Simulation and Estimation of the Mean

    and Uhlenbeck (1930) ( ZO-U [) process, also known as the Vasicek (1977) process I discuss the model briefly, including Matlab code to simulate the process I discuss the estimation of the parameters, in particular the difficult of estimating the speed-of-mean-reversion parameter Again, I include extensive Matlab code for parameter estimation...

  • Estimation of Chaperone

  • Negative binomial distribution

    In this context, and depending on the author, either the parameter r or its reciprocal α is referred to as the "dispersion parameter", "shape parameter" or "clustering coefficient", or the "heterogeneity" or "aggregation" parameter The term "aggregation" is particularly used in ecology when describing counts of individual organisms...
