Abstract
A new Topp–Leone generated family of distributions, which we call the Topp–Leone Discrete Laplace (\(TL-DL\)) distribution, is proposed. It has a shape parameter \(\alpha>0\) and a scale parameter \(0<p<1\). The \(TL-DL\) is an alternative distribution for discrete data that have an asymmetric distribution. Some mathematical properties of the proposed distribution are also derived. Namely, we present the quantile function and the moments for the \(TL-DL\) distribution. The Maximum Likelihood procedure is applied for parameter estimation. An application study is presented using real data. We use two data sets for this part of the analysis to illustrate the applications of the \(TL-DL\) distribution. For the first data set, the change of the stock price in comparison with the closing price for the previous day is considered. The second data set provides information about the comparison of production cycle times of employees before and after the improvement a slippery production line in the degreasing alkaline process by increasing the pressure of the nozzle. The \(TL-DL\) distribution is applied to a real life data and it fits data more efficiently than the Discrete Laplace (\(DL\)) and Discrete Normal (\(DN\)) distributions.中文翻译:
