A Universal Nonparametric Test for Detecting Changes in Trend∗
This paper proposes a nonparametric test for detecting changes in the deterministic component of a dynamic time series model. The testing procedure is based on the asymptotic behaviour of a quasi-likelihood ratio statistic similar to the class of procedures proposed by Fan et al. (2001) for assessing the fit of nonparametric regression models in an iid-error setting. In particular, the test pro...
متن کاملEvaluation of Drought Temporal Changes using Mann-Kendall test and Sen’s Slope in Kerman Province for the Period 1990 to 2018
Investigating the trend of changes in drought as one of the natural disasters is essential. For this purpose, in the present study, the trend of changes in standardized precipitation-evapotranspiration drought index (SPEI) for the synoptic stations of Kerman province was evaluated for the years 1990 to 2018. The change trend of the SPEI time series was evaluated using two both Mann-Kendall and ...

متن کاملAppendix: Mann-Kendall Trend Tests
Kendall Rank Correlation Let (X1, Y1), · · · , (Xn, Yn) be a bivariate random sample of size n. The Pearson correlation coefficient provides an optimal measure of the degree of association between the X’s and the Y ’s when the sample is drawn from a bivariate normal distribution. The Pearson correlation coefficient is reasonably robust for many other distributions as well. The Kendall correlati...
متن کاملQuantifying the trend of vegetation changes using remote sensing (Case study: Fars Province)
Investigating the sustainability of vegetation changes is one of the most important issues of vegetation management in the direction of sustainable development. It is necessary to conduct studies in this regard to select appropriate management for greater compatibility with new conditions. In this research, changes in the vegetation dynamics trend of Fars province were studied using the NDVI in...
