On General Continuous Triangular and Two-sided Power Distributions

In this article, we directly introduce the continuous version of the general discrete triangular distributions (Kokonendji and Zocchi, 2010 Kokonendji, C.C., Zocchi, S.S. (2010). Extensions of discrete triangular distribution and boundary bias in kernel estimation for discrete functions. Statist. Probab. Lett. 80:1655–1662.[Crossref], [Web of Science ®] , [Google Scholar]). It is bounded and, in general, unimodal with pike. It contains thus a very useful class of two-sided power distributions (van Dorp and Kotz, 2002a Van Dorp, J.R., Kotz, S. (2002a). A novel extension of the triangular distribution and its parameter estimation. Statistician 51:1–17. [Google Scholar],b Van Dorp, J.R., Kotz, S. (2002b). The standard two-sided power distribution and its properties; with applications in financial engineering. Amer. Statistician 56:90–99.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2003 Van Dorp, J.R., Kotz, S. (2003). Generalization of two-sided power distributions and their convolution. Commun. Statist. Theor. Meth. 32:1703–1723.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Moments, particular cases, limit distributions, and relations between parameters are straightforwardly derived.
