功能:編寫的計算皮亞諾相關(guān)系數(shù)
開發(fā)語言:ruby
調(diào)用:correlate(x,y)
其中,x,y為需要計算相關(guān)度的向量
調(diào)用示例:
a = [3, 6, 9, 12, 15, 18, 21]
b = [1.1, 2.1, 3.4, 4.8, 5.6]
c = [1.9, 1.0, 3.9, 3.1, 6.9]
c1 = correlate(a,a) # 1.0
c2 = correlate(a,a.reverse) # -1.0
c3 = correlate(b,c) # 0.8221970228
puts c1#,c2,c3
標(biāo)簽：
