Ordinary least square (OLS) in regression has been widely used to analyze patient-level data in cost-effectiveness analysis (CEA). However, the estimates, inference and decision making in the economic evaluation based on OLS estimation may be biased by the presence of outliers. Instead, robust estimation can remain unaffected and provide result which is resistant to outliers. The objective of t...

Penelitian ini menerapkan metode regresi spasial dengan pembobot letak geografis yang merupakan pengembangan dari linier berganda dan diterapkan dalam mengukur faktor-faktor diduga berpengaruh terhadap tingkat pengangguran terbuka di Jawa Timur. Regresi digunakan untuk memodelkan hubungan antara variabel prediktor respon dimana koefisien parameter dihasilkan bersifat global, artinya bahwa semua...

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

Maternal mortality is one indicator to describing prosperity in a country and of women's health. Most the maternal caused by postpartum mortality. The number postpastum events that probability incident small, where depending on certain time or regions with results observation are variable diskrit between independent each other follows Poisson distribution, so proper statistical method regressio...

Parameter estimation is the first step in constructing any control chart. Most estimators of mean and dispersion are sensitive to the presence of outliers. The data may be contaminated by outliers either locally or globally. The exciting robust estimators deal only with global contamination. In this paper a robust estimator for dispersion is proposed to reduce the effect of local contamination ...

ایده فضا - زمان ناجابجایی ncبا پارامتر ?_?? به عنوان تانسوری پاد متقارن و ثابت، اگر چه برای رفع واگرایی فرا بنفش نظریه میدان های کوانتومی مناسب بود، اما نتوانست تقارن لورنتس را حفظ کند. چارچوبی که، پارامتر ناجابجایی را به عنوان مختصاتی از سیستم و حفظ کننده تقارن لورنتس معرفی می کرد، راه حلی برای این چالش جدید بود و توسط doplicher–fredenhagen–roberts–amorim ارائه شد. این چارچوب، معرف فضای ناجا...

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
