[libreoffice-users] VAR, STDEV, CHISQ.INV

Hello guys, I’m having some problems with the VAR and STDEV function, when
executing these lines of code. The average is well calculated but the
remaining two return very low, unrealistic and equal values
(6.93018471335974E-310).

To add to a bad situation, I can’t execute the function CHISQINV as stated
in the second code box below. It gives out the error:

BASIC runtime error.
An exception occurred
Type: com.sun.star.lang.IllegalArgumentException
Message: .

Any help is deeply appreciated!

Thanks,
Rui

====================== CODE BLOCK 1 ======================oRange =
xSheet.getCellRangeByPosition(7, 1,  7, rangeLim)'Media (funciona)
average = oRange.computeFunction(com.sun.star.sheet.GeneralFunction.AVERAGE)
print average'Variancia (ver)
variance = oRange.computeFunction(com.sun.star.sheet.GeneralFunction.VAR)
print variance'StdDev (ver)
stdDev = oRange.computeFunction(com.sun.star.sheet.GeneralFunction.STDEV)
print stdDev

====================== CODE BLOCK 2 ======================
function CHISQINV (erro, degree)        dim oFunction as variant
        oFunction = createUnoService("com.sun.star.sheet.FunctionAccess")
        dim aArgument(1 to 2) as variant
        dim result as double    aArgument(1)=erro
        aArgument(2)=degree     result = oFunction.callFunction("CHISQ.INV",
aArgument())    CHISQINV = resultend function
