modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Building Information Modeling: Road to 2016

A Collaborative Learning Environment for Data Modeling

Data modelling is an important skill tbr students undertaking university courses in computing and Infi~rnlation Systems. It is a complex task which is not currently well provided with tool based support. This paper describes extensions to a learning environment for data modelling which is based on a text based virtual reality panldigm. This learning environment has been enhanced by the inclusio...
