Sir, I found your description of the dataset about nodal involvement in prostate cancer. It comes from the book biostatistics casebook. I like to use the dataset for doing logistics regression. Can you tell me where I can find the dataset. Thanks and greetings Wim van Baarle wvbaarle@wxs.nl [[alternative HTML version deleted]]

Dear Sir, My name is Javier Bussi and I??m a professor at the University of Rosario, Argentina. The National Household Survey has changed the periodicity of the information provided on unemployment from biannual to quarterly. It is not the usual situation where we have two series at the same period of time e.g monthly and quarterly, and we combine both of them. In this case, we have a biannual series that from a certain date changes to quarterly and we want to combine them in order to make forecasts. Do you know any paper where this is discussed? We could make the quarterly series become biannual, but we would be loosing information, we think we can do better than that. Other approach would be to apply structural models with continuos time, but we are trying to find out if there are other alternatives. Thank you very much for your time, Yours sincerely, Javier Bussi ---
