Standard approaches for functional principal components analysis rely on an eigendecomposition of a smoothed covariance surface in order to extract the orthonormal eigenfunctions representing major modes variation set data. This approach can be computationally intensive procedure, especially presence large datasets with irregular observations. In this article, we develop variational Bayesian ap...

multilevel inverters has big placement advantages in power electronics and its application can be mentioned to facts tools such as upfc – d-statcom. therefore, nowadays multilevel inverters have created vast field’s research and researchers are trying to present appropriate structures with fewer keys and greater advantages. the main advantages of multilevel inverters mentioned are low-key volta...

BACKGROUND Disadvantages have already been pointed out on the use of odds ratio (OR) as a measure of association for designs such as cohort and cross sectional studies, for which relative risk (RR) or prevalence ratio (PR) are preferable. The model that directly estimates RR or PR and correctly specifies the distribution of the outcome as binomial is the log-binomial model, however, convergence...
