Calculating Percentage using Groupby

I need to make a table with the percentage of compliance per person. Percentage of compliance is equivalent to the number of YES over the number of rows related to a particular person. How am I suppose to compute this using DAX? I have the idea to use GROUPBY but I don't exactly know how to do it. The data kind of looks like this: 

 Thanks!

    If you directly want a calculated table as an OUTPUT,,, then goto Modelling Tab>>New Table and use this formula

     

    Table =
SUMMARIZE (
    TableName,
    TableName[Person],
    "%age of compliance",
    VAR totalCountforaperson =
        CALCULATE (
            COUNT ( TableName[Person] ),
            ALLEXCEPT ( TableName, TableName[Person] )
        )
    VAR CountwithYes =
        CALCULATE (
            COUNT ( TableName[Person] ),
            FILTER (
                ALLEXCEPT ( TableName, TableName[Person] ),
                TableName[Compliance] = "Yes"
            )
        )
    RETURN
        DIVIDE ( CountwithYes, totalCountforaperson )
)

    Hi Anonymous

     

    The below calculated table will gget you pretty close

     

    New Table = 
    ADDCOLUMNS(
        SUMMARIZECOLUMNS(
            'Table1'[Person],
            "Rows Total",COUNTROWS('Table1') ,
            "Compliant",COUNTROWS(Filter('Table1','Table1'[Compliance]="Yes"))+0
            ),
            "Ratio" , DIVIDE([Compliant],[Rows Total])
            )

      Hi Zubair, thanks for replying! Is the formula above supposed to return a table?

        Hi,

         

        No. Its a MEASURE.

         

        If you put it in a TABLE VISUAL alongwith Names of Persons you will get the desired percentages

         

        Do you need a calcuated table?
