A non-uniform weighted two-components distribution is proposed in the present study for highly right skewed data modeling. We consider a G-GPD model that links a Gaussian distribution to a Generalized Pareto Distribution (GPD) at a junction point, with different weights for each component. It improves a G-GPD model with uniform weights that had been introduced in a preliminary study (see [1]). An...
Right skewed data is available in the field of health science, biological science, epidemiological science and others. This paper assessed some existing procedures for testing the difference of means of two right skewed populations. A Monte Carlo simulation study has been conducted to compare the performance of the test statistics in the sense of empirical size and power of the selected tests. Based...
To present a relatively novel method for modeling length-of-stay data and assess the role of covariates, some of which are related to adverse events. To undertake critical comparisons with alternative models based on the gamma and log-normal distributions. To demonstrate the effect of poorly fitting models on decision-making. The model has the process of hospital stay organized into Markov phases/states...
