Web其实各种变换的作用也不止在于“通项公式”这么简单，但是这样的理解可以让我们泰然接受各种各样的变换，进而去理解很多奇妙的性质，这也就是评论区里一位兄弟所说的“安全感”吧。. 祝研究顺利！. 首先是最常见的理解方法：Z变换是拉普拉斯变换针对 ... WebUsing the Fisher r-to-z transformation, this page will calculate a value of z that can be applied to assess the significance of the difference between two correlation coefficients, r a and r b, found in two independent samples.If r a is greater than r b, the resulting value of z will have a positive sign; if r a is smaller than r b, the sign of z will be negative. check my vehicle service history
