Capture barrier distributions: Some insights and details

Median barrier crash severity: some new insights.

Median barrier is used to prevent cross-median crashes on divided highways. Although it is well documented that crash frequencies increase after installing median barrier, little is known about median barrier crash severity outcomes. The present study estimated a nested logit model of median barrier crash severity using 5 years of data from rural divided highways in North Carolina. Vehicle, dri...

Exp-Kumaraswamy Distributions: Some Properties and Applications

In this paper, we propose and study exp-kumaraswamy distribution. Some of its properties  are derived, including the density function, hazard rate function, quantile function, moments,  skewness  and kurtosis.   Adata set isused to illustrate an application of the proposed distribution. Also, we obtain a new distribution by transformation onexp-kumaraswamy distribution.   New distribution is an...

Some Results on Equilibrium Distributions

‎The equilibrium distributions have many applications in reliability theory, stochastic orderings and random processes. ‎The purpose of this paper is to introduce the equilibrium distributions and presents some results related to this issue. Some results are based on order statistics. ‎In this paper, ‎the generalized Pareto distributions are also analyzed and some basic relationships between t...

Some Details of Nonlinear Estimation

The traditional view adopted by statistics and econometrics texts is that, in order to solve a nonlinear least squares (NLS) or nonlinear maximum likelihood (NML) problem, a researcher need only use a computer program. This point of view maintains two implicit assumptions: (1) one program is as good as another; and (2) the output from a computer is reliable. Both of these maintained assumptions...
