Local dependence in bivariate copulae with Beta marginals

Revista Colombiana de Estadística, 2017
The local dependence function (LDF) describes changes in the correlation structure of continuous bivariate random variables along their range. Bivariate density functions with Beta marginals can be used to model jointly a wide variety of data with ...

On the Noncentral Beta-Distribution

The Annals of Mathematical Statistics, 1955
A computing formula for the noncentral beta-distribution recently published by Nicholson is simplified. A table of figurate numbers is provided to facilitate the use of the simplified formula. It is compared for ease of use with the method of Tang in several situations.

Anomaly Detection in IoT Networks: A Deep Learning Approach Using Autoencoders

IEEE Access
The current fast proliferation of the Internet of Things (IoT) networks has made anomaly detection and security more difficult. Traditional methods are not able to detect hostile activities because they cannot understand dynamic, complex, and high ...

The Modified Beta Weibull Distribution

Hacettepe Journal of Mathematics and Statistics, 2014
A new five-parameter model called the modified beta Weibull probability distribution is being introduced in this paper. This model turnsout to be quite flexible for analyzing positive data and has bathtub andupside down bathtub hazard rate function.Our main objectives are to obtain representations of certain statisticalfunctions and to estimate the ...

A Novel Alternative to the Beta and Kumaraswamy Distributions for Double Bounded Hydroclimatology Data

IEEE Access
The beta distribution is considered the most popular for modeling double-bounded data, such as rates and percentages. But when it comes to double-bounded hydrological data, it often does not show an adequate fit to such data.

Long-Term Temporal Variability of Flowering Day of Red Spider Lily (Lycoris radiata)

Data
In Japan, the flowering of the red spider lily (Lycoris radiata) marks the autumn equinox. To evaluate the effect of climate change on Japanese people’s sense of seasons and this cultural ecosystem service, we examined the spatiotemporal variability of ...

A matrix variate inverse Lomax distribution

Special Matrices
This study presents the matrix variate inverse Lomax distribution as a generalization of the univariate inverse Lomax distribution and shows that this distribution can be derived by using matrix variate gamma distributions.
