(Simulation) Introduction This procedure analyzes the power and significance level of Spearman’s Rank Correlation significance test using Monte Carlo simulation. This test is used to test whether the rank correlation is non-zero. For each scenario that is set up, two simulations are run. One ...

计算斯皮尔曼相关系数前需要先计算向量元素的“秩”(Rank)。对于一个向量,将它的元素按从小到达排序,则对于非重复元素来说,排序后的位置就是它的秩;对于重复元素来说,这些相等元素位置的平均数就是它们的秩。 例如,对下面的m变量: m = c(1, 2, 3, 4, 1, 2, 4) 将其元素按从小到大排列后: sort(m...

We consider rank tests of testing H:F(x)≡G(x) against K:F(x)≥G(x), with strict inequality for some x. D. E. Critchlow [A unified approach to constructing nonparametric rank tests. Tech. Rep. No. 376, Dept. Stat., Stanford Univ. (1986)] suggested a test statistic for testing...
The Spearman rank-order correlation ([r.sub.s]) of the column vector subtests' g loadings with the vector of the sex differences (d) on the subtests indicates the degree to which g is related to the rank order of the sex differences on the various subtests The mean correlation found ...
If you would like some more background information about this test, which does not include instructions for SPSS Statistics, see our more general statistical guide: Spearman's rank-order correlation. Possible alternative tests to Spearman's correlation are Kendall's tau-b or Goodman and Kruskal'...
A Spearman rank correlation is a number between -1 and +1 that says to what extent 2 variables are monotonously related.
