pearson ()
描述：
计算两个向量的pearson相关系数
语法：
pearson(A,B)
备注：
计算向量A和B的pearson相关系数，B缺省为由1到A的序列长度组成的数列。
参数：
|
A |
向量 |
|
B |
向量 |
选项：
|
@r |
计算r2，即pearson(norm@0(A),norm@0(B)) |
|
@a |
@a(…;k)，计算调整后的r2，自由度为k |
返回值：
数值
示例：
|
|
A |
|
|
1 |
=[3,5,2,8] |
|
|
2 |
=[4,6,2,4] |
|
|
3 |
=pearson(A1,A2) |
|
|
4 |
=pearson@r(A1,A2) |
|
|
5 |
=pearson@a(A1,A2;3) |
|
|
6 |
=pearson(A1) |
