Sample Selection,f predictor variables. Even with modern computing facilities it may not be practical to use all of the data available. There will also be cases that are not suitable for model construction, and these need to be identified and dealt with.

Gathering and Preparing Data,predictor variables and a dependent variable. All you had to do was read the data into the modelling software and worry about which data analysis and modelling procedures to apply. You probably didn’t have to give any thought to where the data came from or how it was prepared.

If the production of the list is delayed by a few days, or the model is not quite as good as it could be, then the impact on the business will be relatively small.作者: 有惡意 時間: 2025-3-24 23:02 作者: GLOSS 時間: 2025-3-25 01:27

Peter Hartz,Hilarion G. Petzoldsion systems. A multi-model system is when several different models are constructed to predict a single behaviour. The predictions made by each model are then combined together in some way to deliver a better overall prediction than that generated by any single model on its own.作者: Osteons 時間: 2025-3-26 06:29
Sample Selection,l should be as recent as possible to mitigate against changes in the patterns of behaviour that accumulate over time. For these reasons it is common for models to be constructed using a sub-set (a sample) of the available data, rather than the full population.作者: 進(jìn)取心 時間: 2025-3-26 12:33 作者: 一加就噴出 時間: 2025-3-26 14:01 作者: Ophthalmoscope 時間: 2025-3-26 18:23 作者: 人類學(xué)家 時間: 2025-3-26 22:39

If a model has been constructed as a “proof of concept” or as a standalone research project, this may be a trivial question because nothing needs to be done.

Validation, Model Performance and Cut-off Strategy,Once a model has been constructed, the only way it can be assessed accurately is by using an independent holdout sample. Where a model is going to be applied some time after the development and holdout samples were taken, then it is good practice to also assess the model using an out-of-time sample.
