Performance of Robust Confidence Intervals for Estimating Population Mean Under Both Non-Normality and in Presence of Outliers
We proposed two robust confidence interval estimators, namely, the median interquartile range confidence interval (MDIQR) and the trimean interquartile range confidence interval (TRIQR) for the population mean (µ) as an alternative to the classical confidence interval. The proposed methods are based on the asymptotic normal theorem (ANT) for the sample median (MD) and the sample…
Read More Fire System for an Automated Electrical Substation via Programmable Logic Controller
This article presents the development of an automatism by means of a Programmable Logic Controller (PLC), for the Fire System of an Electric Substation; For this, the areas belonging to the electrical substation are initially described, where the automatism is developed, these being three; Patio area (Transformer location), Distribution board area and Control room. Then…
Read More Permutation Methods for Chow Test Analysis an Alternative for Detecting Structural Break in Linear Models
This study examined the performance of two proposed permutation methods for Chow test analysis and the Milek permutation method for testing structural break in linear models. The proposed permutation methods are: (1) permute object of dependent variable and (2) permute object of the predicted dependent variable. Simulation from gamma distribution and standard normal distribution were…
