2 questions on Smart Analytics (Bank Data) Use Case from App Market2 followers
2 questions on the above mentioned Use Case:
1) In the 'Column Dependencies' for worksheet 'columnDependenciesPurchased' we are only filtering based on the column = 'PurchasedProduct', the value of which could be 'no' or 'yes'.
In the tutorial pdf, we say "the duration of the call had the greatest impact on the number of purchased products". How do we conclude that since we have not checked whether "PurchasedProduct" = 'yes' ?
Is my understanding correct?
2) In the Decision Tree infographics, if I add all the outcomes (all Yes and No) at the leaf nodes, should I not get the exact sample data size that we started with? If I add all the outcomes from the infographics, I get 3404 but our data size is 4521.
Could you please let me know the explanation for this?
thanks & regards,
