Calculating frequencies

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!
