Associating Monthly Hail Occurrence and Large Scale Environment for the 1 Continental United States
4 A new index relating large hail occurrence to environmental parameters has been developed. Hail 5 events are defined as the total number of three-hourly periods in a month that experience one or 6 more instance of hail larger than one inch. The index is derived using Poisson regression between 7 hail events and monthly mean variables describing the large scale environment from the North 8 Ame...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA Large-Scale Linear Regression Sentiment Model
This report details the findings in building a large-scale linear regression sentiment model for an Amazon book review corpus. We studied and applied a number of regression and NLP techniques, including Unigram/Bigrams, stop-word removal, ridge and lasso regression. 1. DATA CORPUS The corpus contains 975194 non-distinct book reviews collected from Amazon by Mark Dredze and others at Johns Hopki...
متن کاملJackknifed Liu-type Estimator in Poisson Regression Model
The Liu estimator has consistently been demonstrated to be an attractive shrinkage method for reducing the effects of multicollinearity. The Poisson regression model is a well-known model in applications when the response variable consists of count data. However, it is known that multicollinearity negatively affects the variance of the maximum likelihood estimator (MLE) of the Poisson regressio...
متن کاملTwo Methods for Measuring the Environmental Returns to Scale Using Data Envelopment Analysis Approach
Nowadays, the assessment of environmental performance has received considerable attention by environmental strategy advocators and decision makers. In recent years, increased emission of CO2 into the air, water pollution, and global warming are universal problems all over the world. Therefore, development of firms with less CO2 emission is an important issue of attention in every area of produc...
