Trend and homogeneity test analysis for rainfall over a 121-year time period in the desert district of Western Rajasthan, India

open access: yesWater Practice & Technology, 2023
The Thar Desert receives very scarce and scanty rainfall; hence, water is given the top priority and importance in daily life. During the past decades, there has been a variation in the trend of the rainfall, climate, and other atmospheric conditions

Trend Analysis Using Mann-kendall And Sen’s Slope Estimator Test for Annual And Monthly Rainfall for Sinjar District, Iraq

open access: yesThe Journal of The University of Duhok, 2020
The time series rainfall data of 70 years (1940 – 2010) of Sinjar District used to identify the trend and slope magnitude of this series. To analyze the trend, the non-parametric test (Mann-Kendall test) and Sen’s slope estimator were used.

Trend Analysis of the Variations of Ambient Temperature Using Mann-Kendall Test and Sen’s Estimate in Calabar, Southern Nigeria

open access: yes, 2021
Studies have been made to understand the fluctuations of temperature in regions around the world because of an ever changing variation due mostly to man’s anthropogenic activities. This study is focused on analysing the temperature variations in Calabar,

Testing for linearity in scalar-on-function regression with responses missing at random [PDF]

open access: yesComputational Statistics, 2024, 2023
A goodness-of-fit test for the Functional Linear Model with Scalar Response (FLMSR) with responses Missing at Random (MAR) is proposed in this paper. The test statistic relies on a marked empirical process indexed by the projected functional covariate and its distribution under the null hypothesis is calibrated using a wild bootstrap procedure.

Assessing Spatial Variability and Trends of Droughts in Eastern Algeria Using SPI, RDI, PDSI, and MedPDSI—A Novel Drought Index Using the FAO56 Evapotranspiration Method

open access: yesWater, 2023
Drought is one of the most severe natural disasters worldwide, but with a particular emphasis in sub-humid and semi-arid climates. Several indices have been created to appropriately identify drought’s characteristics and variability.

Rainfall and Temperature Trend Analysis by Mann–Kendall Test and Significance for Rainfed Cereal Yields in Northern Togo

open access: yesThe Scientist, 2020
This study investigates the trend in monthly and annual rainfall, minimum and maximum temperature (Tmin and Tmax) using the Mann–Kendall (MK) test and Sen’s slope (SS) method and evaluates the significance of their variability for maize, sorghum and ...

Low-rank Panel Quantile Regression: Estimation and Inference [PDF]

open access: yesarXiv, 2022
In this paper, we propose a class of low-rank panel quantile regression models which allow for unobserved slope heterogeneity over both individuals and time. We estimate the heterogeneous intercept and slope matrices via nuclear norm regularization followed by sample splitting, row- and column-wise quantile regressions and debiasing.

Assessing the Impacts of Land Use/Land Cover Changes on Water Resources of the Nile River Basin, Ethiopia

open access: yesAtmosphere, 2023
Land use/land cover change and climate change have diverse impacts on the water resources of river basins. This study investigated the trends of climate change and land use/land cover change in the Nile River Basin. The climate trends were analyzed using
