If the data are related in a nonlinear way (for example, in a U-shaped relationship), the absolute value of the correlation coefficient will suffer downward bias (will underestimate this relationship). An alteration of this basic framework for nonlinear relationships is discussed later. For even ...
Correlation coefficient at a meteorological station in Iran based on Kendall's test is 0.8 for PERSIANN while it is 0.4 and 0.5 for two interpolation methods, Inverse Distance Weighting and Kriging respectively. A simple evaporation/transpiration scheme (SETS), which is a distributed land surface ...
Two-Sample Intraclass Correlation Coefficient Tests for Matrix-Valued Data doi:10.1007/978-3-031-69622-0_4Under a model having a Kronecker product covariance structure with compound symmetry or circular symmetry, two-sample hypothesis testing for the equality of two correlation parameters is considered...
This paper presents how to apply the sample selection technique to measurements of the correlation coefficient in dual antenna measurements, for example, for diversity or MIMO applications. Theoretical background and useful mathematical relations are presented. The application is verified through ...
