How can I start???
My problem is that I want to apply association rules to a DB of a supermarket, but this data have to be cleaned (data preprocessing) and I don't know how to make this.
So, for an idea the DB has the follow items:
numero(Bill_Number) fecha(date) codigo(ProductCode) costo(Cost) precio(Price) tarifa_iva(Value-added Tax Rate) ->
precio_sin_iva(Price_whitout_Value-added tax) valor_iva(Value_Value-added tax) cantidad(Amount) valor_item(Value_item) ->
bodega(storeRoom) nombre(ProductName) nclasifica1(ClassificationNane) clasifica1(ClassificationCode) ->
The data for this are:
216932 31/08/2008 4756 2531.66 3200.00 16.00 2758.62 441.38 10.000 3200.00 1 MARGARINA PRACTIS X 400 GR LLOREDA DISTRIBUCIONES 70 MARGARINAS 90
Please if you can help me about what must I to apply for clean the data or has it of the correct form by apply fp growt then association rules.
Thank you by the attention.
