Copula analysis was created to explain the dependence of two or more quantitative variables. Due need for in-depth data involving complex variable relationships, there is always a new copula models with original features. As modern example, circular periodic types, trigonometric copulas are particularly attractive and recommended. This is, however, an underexploited topic. In this article, we p...

The generalized half-logistic distribution is ideal to fit the lifetime of some products, such as ball bearings and electrical insulation. In this paper, we aim extend scope by creating a motivated bivariate version. We thus introduce using Farlie Gumbel Morgenstern (FGM) copula, which called FGM (FGMBGHLD for short). particular, FGMBGHLD finds application in describing datasets that have weak ...

We model the recursive moments of aggregate discounted claims, assuming inter-claim arrival time follows a Weibull distribution to accommodate overdispersed and underdispersed data set. use copula represent dependence structure between its subsequent claim amount. then Laplace inversion via Gaver-Stehfest algorithm solve numerically first second moments, which takes form Volterra integral equat...

Manufacturing for a multitude of continuous processing applications in the era automation and ‘Industry 4.0? is focused on rapid throughput while producing products acceptable quality that meet customer specifications. Monitoring stability or statistical control key process parameters using data acquired from online sensors fundamental to successful manufacturing applications. This study addres...

Analyzing the future values of anticipated claims is essential in order for insurance companies to avoid major losses caused by prospective claims. This study proposes a novel three-parameter compound Lomax extension. The new density can be "monotonically declining", "symmetric", "bimodal-asymmetric", "asymmetric with right tail", wide peak" or left tail". hazard rate take following shapes: "J-...

This study attempts to reveal the consequences of coronavirus disease 2019 (COVID-19) on micro, small, and medium enterprises (MSMEs) in Chiang Mai, Thailand. A total 786 MSMEs were surveyed during May August 2022, corresponding period when recovery businesses livelihoods from ongoing COVID-19 crisis became more perceptible. The perceptions COVID-19’s impact their survivability are explored inv...

In survival analyses, infections at the catheter insertion site among kidney patients using portable dialysis machines pose a significant concern. Understanding bivariate infection recurrence process is crucial for healthcare professionals to make informed decisions regarding management protocols. This knowledge enables optimization of treatment strategies, reduction in complications associated...

This study analyzes the physical layer security (PLS) performance of a differential chaos shift keying (DCSK) modulation-based Power Line Communication (PLC) system by exploiting novel Farlie-Gumbel-Morgenstern (FGM) Copula approach. A power line Wyner’s wiretap channel model is investigated, where main and are assumed to be correlated Log-normally distributed. The Gamma approximation Log-norma...

Although the use of nonparametric or parametric methods to construct a probability distribution from an actual data has become widespread in economics, procedure based on the entropy principle of Shannon (1948), and popularized by (Jaynes, 1957) provides a promising alternative as a method to recover a probability density that yields the highest level of uncertainty (i.e., randomness) from limi...

Within the developing vertebrate head, the organisation of skeletal structures and peripheral nerves depends on the orchestrated migration of pluripotent cranial neural crest cells (NCCs) through the cranial mesenchyme (Bronner-Fraser, 1995; Le Douarin, 1982). Cranial NCCs are generated throughout the dorsal hindbrain (Sechrist et al., 1993) but their emigration into the adjacent mesenchyme is ...
