چکیده

AbstractIn this paper, a new three-parameter distribution, which is member of the Alpha Power Transformed Family distributions, introduced. The distribution generalization logistic model called alpha power transformed (APTL) distribution. Some mathematical properties like moments, quantile function, median, skewness, kurtosis, Rényi entropy, and order statistics are discussed. parameters estimated using maximum likelihood estimation method simulation study performed to investigate effectiveness estimates. usefulness flexibility APTL in modelling financial data investigated two portfolio stock indices, namely NASDAQ New York both from United States market. Based on selection criteria, we able establish empirically that best for sets, among various distributions compared study. For each data, value-at-risk estimates give smaller expected loss at high confidence levels comparison those other distributions.Keywords: family distributions; distribution; estimation; investments; value-at-risk. AbstrakPada artikel ini, diperkenalkan distribusi baru dengan tiga parameter yang merupakan anggota dari keluarga Transformed. Distribusi ini generalisasi logistik disebut Transform Logistics (APTL). Selain itu, dibahas pula beberapa sifat matematika tersebut yaitu momen, fungsi kuantil, kemiringan, entropi Rényi, dan statistik terurut. Parameter diestimasi menggunakan metode studi simulasi dilakukan untuk menyelidiki keefektifan estimasi. Kegunaan fleksibilitas dalam pemodelan keuangan diselidiki dua indeks saham portofolio pasar Amerika Serikat York. Berdasarkan kriteria pemilihan model, secara empiris, dihasilkan bahwa adalah terbaik memodelkan set di antara berbagai dibandingkan pada penelitian ini. Untuk setiap estimasi kuantil memberikan kerugian diharapkan lebih kecil tingkat kepercayaan tinggi lainnya.Kata Kunci: transformed; logistik; investasi portofolio; 2020MSC: 62E10.

The Long Term Fréchet Distribution: Estimation, Properties and Its Application

Although the GEV distribution is the most used generalization of the Fréchet model, other distributions has been proposed in the literature. De Gusmão [2] proposed a three parameter generalized inverse Weibull distribution in which includes the Fréchet distribution. Krishna et al. [3] proposed the MarshallOlkin Fréchet distribution. Barreto-Souza et al. [4] discussed some results for beta Fréch...

Power Normal-Geometric Distribution: Model, Properties and Applications

In this paper, we introduce a new skewed distribution of which normal and power normal distributions are two special cases. This distribution is obtained by taking geometric maximum of independent identically distributed power normal random variables. We call this distribution as the power normal--geometric distribution. Some mathematical properties of the new distribution are presented. Maximu...

Estimation of Parameters for an Extended Generalized Half Logistic Distribution Based on Complete and Censored Data

This paper considers an Extended Generalized Half Logistic distribution. We derive some properties of this distribution and then we discuss estimation of the distribution parameters by the methods of moments, maximum likelihood and the new method of minimum spacing distance estimator based on complete data. Also, maximum likelihood equations for estimating the parameters based on Type-I and Typ...
