This example explains how to compute a Kendall Correlation:cor(x, y, method = "kendall") # Kendall correlation # [1] 0.4719192As shown in the previous R code, we had to set the method argument to be equal to “kendall”.Example 3: Using cor() Function to Calculate Spearman Correlation...
Correlation matrix A solution to this problem is to compute correlations and display them in a correlation matrix, which shows correlation coefficients for all possible combinations of two variables in the dataset. For example, below is the correlation matrix for the dataset mtcars (which, as...

摘要: We describe a method for calculating dynamical spin-spin correlation functions in the isotropic and anisotropic antiferromagnetic Heisenberg models. Our method is able to produce results with high accuracy over the full parameter space.关键词: correlation functions integrable spin chains ...
confident that you know what that true proportion is. These confidence interval techniques can be applied to find the exact confidence interval of a mean in R, calculate confidence interval from a p value, or even compute an exact confidence interval for variance in R from a sampling ...
