Estimation of Parameters of Two Non-linear Regression Models Using Assumed Values: Reciprocal Power Regression Models

Emmanuel O. Biu & Nduka Wonu · Asian Research Journal of Mathematics · 2020

Fitting nonlinear models is not a single-step procedure but it involved a process that requires careful examination of each individual step. Depending on the objective and the application domain, different priorities are set when fitting nonlinear models; these include obtaining...

Detection of Non-Normality in Data Sets and Comparison between Different Normality Tests

Emmanuel O. Biu, Maureen T. Nwakuya & Nduka Wonu · Asian Journal of Probability and Statistics · 2020

The paper provides five tests of data normality at different sample sizes. The tests are the Shapiro-Wilk (SW) test, Anderson-Darling (AD) test, Kolmogorov-Smirnov (KS) test, Ryan-Joiner (RJ) test, and Jarque-Bera (JB) test. These tests were used to test for normality for two sec...
