## Sample Calculations

These templates may be useful starting poitns for your own calculations. You should replace the Dimension, Hierarchy, Level and Measure names with your own.

### todo

### IRR, MIRR, NPV

These functions accept a list of values as an argument, not a set of tuples and a value expression like Sum(), Avg() etc.

For these to work you should specify the member of measures to use so that the calculation does not reference itself.

This will evaulate the values for "My Set" in the context of the IRR measure which can not work.
`IRR( MySet )`

Instead reference the measure you want to calculate for and create a set with that member in.
`IRR( { [Measures].[My Measure] } * MySet )`
