When average value and variance approximately equal selects the Poisson model suitably; When distributes quite separate, the suitable choice negative binomial or the zero pile up the Poisson model; When the accident data manifests the many zero value, should choose the zero to pile up the Poisso...
One difficulty involved in testing the social brain hypothesis in insects is that many of the model species used in cognition studies are highly social (eusocial), and comparatively little work has been done in insects that live in less integrated social structures or that are solitary. As more...
Then the sum is almost surely finite, and the normalisation is a Poisson-Dirichlet process. Again, we prove this proposition below the fold. Now we turn to the second way (a topic, incidentally, that was briefly touched upon in this previous blog post): Proposition 3 (Large cycles of a ...
What is Regression?: Regression is a statistical technique used to analyze the data by maintaining a relation between the dependent and independent variables.
However, there is a complication: these band energies are not solely coming from the semiconductor, but also contain a contribution that comes from electrostatic effects from the electrons and holes, and more specifically by solving the Poisson equation where is the dielectric constant of the ...
3. Poisson Distribution This discrete probability distribution expresses the number of events that happen within a given space or time. It has quite a number of applications within the insurance, finance and traffic engineering industries. The formula for the Poisson distribution is as follows: ...

This section provides a quick introduction of speed, which is a mathematical model used to describe our universe in frame of references that combines space and time together.
awhere s, v, k,3,q,w and 5 are defined as in Bate’s model, r is the risk-free interest rate, 1 and 2 are independent Poisson processes with constant intensities uand v respectively.y is the jump size of the asset price return with density 0 and 7 and 9 is the jump size...
A chi-square (χ2)statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample. For example, the results of...
