Factor Analysis with Poisson Output
نویسندگان
چکیده
We derive a modified version of factor analysis for data that is poisson (rather than gaussian) distributed. This modified approach may better fit certain classes of data, including neuronal spiking data commonly collected in electrophysiology experiments.

Delay Analysis for a TDMA Channel with Contiguous Output and Poisson Message Arrival
Absiruct-An analysis of the exact delay of a TDMA or a loop communication system with a contiguous output and a Poisson message arrival process is presented. The nonlinear relationship of a contiguous output with arbitrary arrival process can be expressed by an i finite series. In the case of a Poisson message arrival process, the series can be summed to a closed form. The derived result, which...

Introduction: To estimate the accuracy levels of Lagrange, Newton backward interpolation, and linear interpolation methods in estimating the output factors for square fields used in linear accelerator for 6 MV photons at various depths. Materials and Methods: Ionization measurements were carried out in radiation field analyzer in linear accelerator for 6 MV beams at the depths of 5 and 10 cm by...
متن کاملThe Factors Affecting on Banking Crisis Loss with Emphasis on Policy Frameworks
The main purpose of this study is to identify the determinants of banking crisis loss, the variables of policy framework especially, for 12 sample countries over the period 1980-2019. Accordingly, we extracted pre-crisis and post-crisis trends from countries' real GDPs and then calculated output loss for the crisis year and three years afterwards. In the following, we used the Poisson quasi-max...
متن کاملDetermining the correlated factors of breast cancer recurrence by Poisson Beta-Weibull non- mixture cure model
Introduction: Therapies for many of diseases, especially cancer, have been improved significantly in the recent years, resulting in an increase in the number of patients who do not experience mortality. Therefore, the application of cure models is more suitable for survival analysis in this population than the usual survival models are. The aim of this study was to estimate the recurrence-free ...
متن کاملHigh Q Power Divider/Combiner with High Output Isolation using Substrate Integrated Waveguide Technology
A power divider (PD)/ power combiner (PC) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (SIW) technology is proposed. An SIW cavity is designed to provide a high quality factor filtering response and an SMD resistor is attached between two output ports to realize the high isolation. The value of the applied resistor is calculated by using the ...
