Analysis Of Intervalcensored Or Aggregated Point Process Data: A Local Likelihood Approach,Used
Delivery time: 8-12 business days (International)
The use of local likelihood methods (Tibshirani and Hastie, 1987; Loader, 1996) in the presence of intervalcensored or aggregated data leads to a natural consideration of an EMtype strategy, or a local EM algorithm. We consider local EM to analyze point process data that are either intervalcensored or aggregated into counts. We present the formulation of local EM algorithms to estimate density, intensity and risk and their implementations using piecewise constant functions. It is shown that the use of the piecewise constant function at the Estep explicitly results in an iteration that involves an expectation, maximization and smoothing step, or an EMS algorithm considered in Silverman et al. (1990). Consequently, we reveal a previously unknown connection between local EM and the EMS algorithm. From a theoretical perspective, local EM and the EMS algorithm complement each other. We demonstrate that an EMS algorithm rises naturally from a local likelihood consideration in the context of point processes while the EMS algorithm serves as a rapid implementation of local EM algorithms and provides theoretical tools to better understand the role of local EM.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
