The study of rocks and minerals is very common for researchers in the field of science. However, in the context of real-life, inmense amounts of data exist related to the orientation of rocks and minerals which are often measured in terms of angles wherein their range is defined in [0, π). Thus, to deal with such types of datasets, a new semi-circular probability distribution has been introduced in this research by using the method of inverse stereographic projection (ISP), named as the semi-circular generalized Lindley (SCGL) distribution. Characteristic function and fundamental properties of the newly developed distribution are also studied. Method of maximum likelihood estimation is used to estimate the values of the parameters and . The applicability of the proposed distribution is shown by modelling 60 angular observations of feldspar laths in basalt and the orientation of pebbles.
El estudio de las rocas y minerales es muy común entre los investigadores en el campo de las ciencias. Sin embargo, en la práctica, existe una gran cantidad de datos relacionados con la orientación de las rocas y minerales, que a menudo se miden en términos de ángulos cuyo rango se define en [0, π). Por lo tanto, para abordar este tipo de conjuntos de datos, en esta investigación se introduce una nueva distribución de probabilidad semicircular utilizando el método de proyección estereográfica inversa (ISP), denominada distribución semicircular generalizada de Lindley (SCGL). También se estudian la función característica y las propiedades fundamentales de la distribución recientemente desarrollada. Se utiliza el método de máxima verosimilitud para estimar los valores de los parámetros. La aplicabilidad de la distribución propuesta se demuestra mediante la modelización de 60 observaciones angulares de laths de feldespato en basalto y la orientación de material de arrastre.
