Hi All

I need to calculate some frequencies.

Lets say I have an exampleSet with attributes Gender, Age and N. N is the number of people with a given gender and age. I need a new exampleSet with attributes Age and MaleFreq. Any easy method?

regards
Peter

    You can filter the Example Set using the operator "Filter Examples". Keep Gender==Male.

    (From what I understand from your question the aggregations has already been done).

    Thanks!

    But how do I calculate MaleFreq? For a given age, It should be something like MaleFreq = N(Male)/(N(Male)+N(Female)). How is that possible?

    Hi,

    You might also find the 'Aggregate' operator useful, curiously.

    Hope so!
