- Explain the difference between a training data set and a validation data set. Why are these data sets used routinely with data mining techniques in the XL Miner® program and not used in the ForecastX Program? Is there, in fact, a similar technique presented in a previous chapter that is much the same as partitioning a data setExplain the procedures used to measure reliability and validity of data1. What is the measure of central tendency suitable for summarising the data on ice cream flavours?
