Analysis of Migration Trends in Zimbabwe Using Mann-Kendall and Sen’s Slope Tests

open access: yesScience Journal of Applied Mathematics and Statistics, 2021
The movement of people into and out of the Zimbabwean borders has become a topical issue in every sector of the country. The main devastating movement is when a lot of skilled professionals leave the country to other countries in search of greener pastures without ploughing back home and left the country of origin with few or no skilled personnel to ...

pyMannKendall: a python package for non parametric Mann Kendall family of trend tests. [PDF]

open access: yesJournal of Open Source Software, 2019
El análisis de tendencias es una de las mediciones más importantes en el estudio de los datos de series de tiempo. Tanto las pruebas paramétricas como las no paramétricas se utilizan comúnmente en el análisis de tendencias. Las pruebas paramétricas requieren que los datos sean independientes y se distribuyan normalmente.

The modified Mann-Kendall test: on the performance of three variance correction approaches [PDF]

open access: yesBragantia, 2013
The Mann-Kendall test has been used to detect climate trends in several parts of the Globe. Three variance correction approaches (MKD, MKDD and MKRD) have been proposed to remove the influence of serial correlation on this trend test. Thus, the main goal of this study was to evaluate the probability of occurrence of types I and II errors associated ...
