Parameter Estimation for Differential Equations: A …

We propose a new method for estimating parameters in non-linear differential equations. These models represent change in a system by linking the behavior of a derivative of a process to the behavior of the process itself. Current methods for estimating parameters in differential equations from noisy data are computationally intensive and …

Negative binomial distribution - Wikipedia

In probability theory and statistics, the negative binomial distribution is a discrete probability distribution of the number of successes in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of failures (denoted r) occurs.For example, if we define a 1 as failure, all non-1s as successes, …

Estimation of ODM is the second sub model of the classical four model for the Urban Transportation Planning Process (UTPP). As illustrated in Fig. 1, this model is composed of four sub models.The first one is the trip generation sub model, which consists on determining the traffic attracted and produced from each zone.

Risks For the Long Run: Estimation with Time …

This paper develops a method to simultaneously estimate the model parameters and the decision interval of the agent by exploiting identifying restrictions of the Long Run Risk (LRR) model that account for time aggregation. The LRR model finds considerable empirical support in the data; the estimated decision interval of the agents is 33 days. Our estimation …

We propose a variational aggregation method for optical flow estimation. It consists of a two-step framework, first estimating a collection of parametric motion models to generate motion candidates, and then reconstructing a global dense motion field. The aggregation step is designed as a motion ...
