Testing of Hypotheses on a Multivariate Population: Some of the Variates Being Continuous and the Rest Categorical [PDF]
The Egyptian Statistical Journal, 1958 We consider a (k+1)-variate distribution in which k variates are continuous and I variate are categorical. The k variates are assumed to have a conditional multivariate normal distribution with respect to the I categorical variates which are assumed to ...

An Extension of the Truncated-Exponential Skew- Normal Distribution
Mathematics, 2021 In the paper, we present an extension of the truncated-exponential skew-normal (TESN) distribution. This distribution is defined as the quotient of two independent random variables whose distributions are the TESN distribution and the beta distribution ...

COVID-19: Nothing is Normal in this Pandemic
Journal of Epidemiology and Global Health, 2021 This manuscript brings attention to inaccurate epidemiological concepts that emerged during the COVID-19 pandemic. In social media and scientific journals, some wrong references were given to a “normal epidemic curve” and also to a “log-normal curve ...

Evaluating the Normal Distribution
Journal of Statistical Software, 2004 This article provides a little table-free C function that evaluates the normal distribution with absolute error less than 8 x 10 -16 . A small extension provides relative error near the limit available in double precision: 14 to 16 digits, the limits ...

Extended Generalized Sinh-Normal Distribution
Mathematics, 2021 Positively skewed data sets are common in different areas, and data sets such as material fatigue, reaction time, neuronal reaction time, agricultural engineering, and spatial data, among others, need to be fitted according to their features and maintain

Improving the Performance of Turbo-Coded Systems under Suzuki Fading Channels
Journal of Low Power Electronics and Applications, 2019 In this paper, the performance of coded systems is considered in the presence of Suzuki fading channels, which is a combination of both short-fading and long-fading channels.

The Extended Half-Skew Normal Distribution
Mathematics, 2022 A new class of densities for modelling non-negative data, which is based on the skew-symmetric family of distributions proposed by Azzalini is introduced.We focus on the model generated by the skew-normal distribution, called Extended Half Skew-Normal ...
