In this lecture, we explain how to derive the maximum likelihood estimator (MLE) of the parameter of a Poisson distribution. Revision materialBefore reading this lecture, you might want to revise the pages on: maximum likelihood estimation; the Poisson distribution. ...

we consider the simultaneous estimation of the parameters (means) of the independent Poisson disrribution by using the following loss functions: L0(θ,T)=n∑i=1(Ti-θi)2,L1(θ,T)=n∑i=1(Ti-θi)2θi We develop an estimator which is better than the maximum likelihood estimator X sim...
Indeed, Poisson is the only QML estimator that preserves total trade flows. This result is an additional reason for preferring Poisson as a workhorse gravity model estimator.关键词: international trade gravity model poisson quasi-maximum likelihood estimator ...
Maximum Likelihood estimator, Moments estimator, Percentile estimator, least square estimator and weighted least square estimator. An empirical study is conducted to compare among these methods performances. We also consider the generating issue. Other empirical experiments are conducted to build a model ...
In this paper, Zero-truncated Poisson distri- bution and zero-truncated Negative Binomial distribution were introduced. The eigenvalue, expectation and variance of these two truncated distributions were deduced. likelihood estimator of parameter of zero-truncated Negative binom- ial distribution was obtaine...
By using a maximum likelihood method, we calculated the mean of the Poisson distribution that best fits the data. By dividing this mean by the number of generations (50100) from the date of the population founding, we deduced that rate of recombination in the MHC is approximately 0.004 to ...
