Abstract
فى هذا البحث يتناول الباحثان بالدراسة توزيع احتمالي جديد يُسمى Burr X exponentiated Fréchet Distribution. تم اشتقاق العديد من الخصائص الإحصائية والرياضية للتوزيع الجديد منها العزوم حول الصفر والدالة المولدة للعزوم والعزوم الاحتمالية والإحصاءات الترتيبية وغيرها من الخصائص. استخدمت طريقة الإمكان الأعظم لتقدير معالم التوزيع المجهولة. تم تقييم أداء طريقة الإمكان الأعظم عن طريق دراسة محاكاة. تمت مقارنة التوزيع الجديد مع امتدادات أخرى لتوزيع منافسه باستخدام عينتين من البيانات الفعلية.
Abstract
In this paper, we study a new model called the Burr X exponentiated Fréchet Distribution. The new model exhibits unimodal, unimodal then buthtab and buthtab hazard rates. Various properties of the new model are explored including moments, generating function, probability weighted moments, Stress-strength model and order statisics. The maximum likelihood method is used to estimate the model parameters. Simulation results to assess the performance of the maximum likelihood estimates are discussed. We compare the flexibility of the proposed model with other extensions of the Fréchet distribution by means of two real data sets.
