In this paper, we propose a stochastic approximation to the well-studied expectation–maximization (EM) algorithm for finding the maximum likelihood (ML)-type estimates in situations where missing data arise naturally and a proportion of individuals are immune to the event of interest. A flexible f...
To solve above question, we should use EM algorithm, which has two parts: E(Expection) part and M(Maximum) part. E part: calculating the exception of the likehood function with respect to hidden parameter. M part: finding the right exposed parameters that maximize the expection.And go back...

In the case when a negative value of the variance component parameter is not allowed, Verbeke and Molenberghs (2003) discuss the use of one-sided tests, in particular the score test. In the context of a generalized nonlinear mixed model (to be discussed), Vonesh and Chinchilli (1997, ...

Current methods use iterative fitting of focus-dependent simulated power spectra to the power spectra of experimental images, with the fitting performed independently for different images. Here we have developed a novel graph theory based method in which the rotational average focus and individual ...

It has recently been suggested that the use of distributions indexed by skewness/shape parameters produce more flexibility in the modelling of different applications. Consequently, the results show a more realistic interpretation for these problems. For these reasons, the aim of this paper is to ...
