我需要协方差计算的帮助/指导。我编写了以下程序来计算 10 年股票数据的协方差。问题是我收到一个错误，指出下标超出范围。我调用函数的方式是
CalcCovarAll firstColPick:=17, SecColPick:=17, ColPrint:=42
'firstColPick 是第一列pick的地址
'secColPick 是第二列pick的地址
'colPrint 是将输出打印到单元格的特定列上。
任何快速帮助都会非常有帮助。我认为我没有正确实现该功能
Sub CalcCovarAll(ByVal firstColPick As Integer, ByVal SecColPick As Integer, ByVal ColPrint As Integer)
Dim secondPick As Range
Dim secondValue As Variant
Dim firstPick As Range
Dim firstValue As Variant
Dim wksSheet As Worksheet
Dim rowPrint As Range
Dim cvaluePrint As Variant
Dim Row As Integer
Dim col As Integer
'setting up the active worksheet
Set wksSheet = Workbooks("VaR_cw2 (2).xlsm").Worksheets("Sheet1")
'setting up the pickup of first column
Set firstPick = Range(Cells(4, firstColPick), Cells(2873 + 1, firstColPick))
firstValue = firstPick.Value
'setting up pickup of second column
Set secondPick = Range(Cells(4, SecColPick), Cells(2873 + 1, SecColPick))
secondValue = secondPick.Value
'setting up column printing
Set rowPrint = Range(Cells(5, ColPrint), Cells(2873 + 1, ColPrint))
cvaluePrint = rowPrint.Value
For Row = LBound(secondValue) To UBound(secondValue) - 1
cvaluePrint(Row + 1, 1) = Application.Covar(firstValue, secondValue)
Next Row
rowPrint = cvaluePrint
End Sub
