Moving average by month / moving variance

Hi guys,

 

I need to calculate the average considering that: The previous months of 12, has average by the quantity of month. So if I have 6 months, the average is replicated to the previous months, if I have 7,8,9,10,11 and 12 months I have the average replicated to the previous months. If it has 13 months, I need to calculate the moving average by 12 months (this is working).

 

So, considering the image, I need that AVG2 has the value 0.366333333 to index minors that 13.

 

Need Help

    Use this measure :

    New Avg = 
VAR IND = SELECTEDVALUE('Table'[Index])
VAR _12 = 
    CALCULATE(
        AVERAGE('Table'[Value]),
        'Table'[Index] <= 12,
        ALLSELECTED('Table')
)

VAR _OVER12 = 
    CALCULATE(
        AVERAGE('Table'[Value]),
        'Table'[Index] <= IND && 'Table'[Index] > IND - 12  
        ,ALLSELECTED('Table')
    )

RETURN

IF( IND > 12,
    _OVER12,
    _12
)
