svyranktest(ResultA ~ IndependantVariableA, design = surveydesign, test = "wilcoxon")
Error in solve.default(V, beta) :
system is computationally singular: reciprocal condition number = 1.0448e-21
我正在尝试在 IndependantVariableA(连续)和 ResultA(因子)上运行 Wilcoxon 秩检验。更高级别的 IndependantVariableA 可能与更高级别的 ResultA 相关,但是当我尝试运行 wilcoxon 测试时,我不断收到该错误。
