maxifs 2010 min - Excel MAXIF function or emulation?




3 Answers

You can use an array formula.In the cell in which you want the max calculated enter: =Max(If([test],[if true],[if false]) where you replace the values in square brackets with the test, what to return if true and what to return if false. For example:

=MAX(IF(MOD(A2:A25,2)=0,A2:A25,0)

In this formula I return the value in column A if the value divided by 2 has no remainder. Notice that I use a range of cells in my comparison and in the value if false rather than a single cell.

Now, while still editing the cell, hit Ctrl+Shift+Enter (hold down the Ctrl key and the Shift together and then hit enter).

This creates an array formula that acts on each value in the range.

EDIT BTW, did you want to do this programmatically or manually? If programmatically, then what environment are you using? VBA? C#?

EDIT If via VBA, you need to use the FormulaArray property and R1C1 references like so:

Range("A1").Select
Selection.FormulaArray = "=MAX(IF(MOD(R[1]C:R[24]C,2)=0,R[1]C:R[24]C,0))"
multiple criteria

I have a moderately sized dataset in excel from which I wish to extract the maximum value of the values in Column B, but those that correspond only to cells in Column A that satisfy certain criteria.

The desired functionality is similar to that of SUMIF or COUNTIF, but neither of those return data that is necessary. There isn't a MAXIF function; how do I emulate one?




A limitation with the code provided thus far is that you are restricted to 2 conditions. I decided to take this code further to not restrict the number of conditions for the MaxIfs function. Please see the code here:

        Function MaxIfs(MaxRange As Range, ParamArray Criteria() As Variant) As Variant
        Dim n As Long
        Dim i As Long
        Dim c As Long
        Dim f As Boolean
        Dim w() As Long
        Dim k As Long
        Dim z As Variant

        'Error if less than 1 criteria
        On Error GoTo ErrHandler
        n = UBound(Criteria)
        If n < 1 Then
            'too few criteria
            GoTo ErrHandler
        End If
            'Define k
            k = 0            

        'Loop through cells of max range
        For i = 1 To MaxRange.Count

        'Start by assuming there is a match
        f = True

            'Loop through conditions
            For c = 0 To n - 1 Step 2

                'Does cell in criteria range match condition?
                If Criteria(c).Cells(i).Value <> Criteria(c + 1) Then
                    f = False
                End If

            Next c

            'Define z
            z = MaxRange

            'Were all criteria satisfied?
            If f Then
                k = k + 1
                ReDim Preserve w(k)
                w(k) = z(i, 1)
            End If

        Next i

        MaxIfs = Application.Max(w)

        Exit Function
        ErrHandler:
        MaxIfs = CVErr(xlErrValue)

    End Function

This code allows 1 to multiple conditions.

This code was developed with reference to multiple code posted by Hans V over at Eileen's Lounge.

Happy coding

There are lots of ways to accomplish this - The one I came up with used array formulas. Type this in:

=MAX((--(A:A=A1))*(B:B))

And then hit Ctrl+Shift+Enter to make it an array formula

Hope this does the trick
