1. The Poisson distribution can be used to model a continuous random variable. a. True b. False 2. Another name for the mean of a probability distribution is its expected value. a. True b. False 3. The largest value that a Poisson random ...
Consider the Poisson distribution with parameter lambda. Find the maximum likelihood estimator of lambda based on a sample of size n. The customer arrivals to a grocery store follow a Poisson distribution, but the rate is unknown. The arrivals are observed ...
The EE distribution is obtained by mixing exponential and gamma distributions. The probability density function (pdf) of the EE distribution is given by 𝑓(𝑥)=𝛼2(1+𝛽𝑥)𝑒−𝛼𝑥𝛼+𝛽,𝑥>0,𝛼>0,𝛽≥0.f(x)=α2(1+βx)e−αxα+β,x>0,α>0,β≥0. (...
Finally, we construct a flexible count data regression model based on the proposed distribution with two practical examples. Keywords: discrete statistical model; dispersion index; hazard rate function; parameter estimation; simulation; regression MSC: 62E15 1. Introduction In recent decades, count ...
Equations (9) and (10) can be solved numerically for 𝜃θ and 𝜇μ using the Newton–Raphson iteration; for example, starting from the seed point 𝜃θ near to zero, with 𝜇=𝑡̲+1μ=t¯+1. Simulation Study The accept-reject sampling method can be used to generate random va...
Many examples can be found in the literature. The simplest renewal process, the Bernoulli process, has been used in [4] for example. In this case, the I T ’s are geometrically distributed. Its continuous counterpart, the Poisson process, has been used for its simpler mathematical ...

The knowledge of the equations which govern the system’s evolution allows the full mathematical description of the evolution space, even when these equations are not yet solved. Moreover, the symmetry properties of the evolution space are the same as those of the manifold of motions. For examp...
