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...
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...
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 ...
In Simmons' experience, we'll find that even a genius like him took a full ten years to reach the “Holy Grail” of the Renaissance Fund. So what is this Holy Grail? four Simmons said: “I'm Mr. Model, and I don't want to do fundamental analysis. One of the advantages of model...
What is Regression?: Regression is a statistical technique used to analyze the data by maintaining a relation between the dependent and independent variables.

The Poisson Model Assumptions a. The average rate of events per unit time is constant. This means the number of people who visit your blogper hourmight not follow a Poisson Distribution, because the hourly rate is not constant (higher rate during the daytime, lower rate during the nighttime)...
aThus, for the random component of a Poisson log-multiplicative model, the response variable follows a Poisson-distribution with the parameter μijt, where μijt represents the expected value of the response variable (i.e., yijt~Pois (μijt), meaning that yijt=E(yijt)+εijt=μijt+εijt...
