>>>"Median" ? Is it the value sitting in middle in a series ? If so and number of elements <= 65000 a simple way might be :
>>>
select myValue into array myArray where !isnull(myValue)
>>>if type("myArray") # "U"
>>> if alen(myArray,1) > 1
>>>    return myArray[floor(alen(myArray,1)/2) + 1]
>>> else
>>>    return myArray[1]
>>> endif
>>>endif
>>>return .null.

>>Hi Cetin,

>>Median is a value in a series of numbers where there are an equal number of values less than and greater than. Not knowing if there may be duplicate values makes this a bit harder. I'd try for the arithmetic mean (by getting the minimumand maximum values via CALCULATE) as a starting point. Where to go from there, I haven't figured out.:-)
