HI,

This will be a broad question and difficult answer, you are expecting the entire DP in one question. i will try to summerise the same,

1. we have forecast profiles - Univariate, Causal and composite

2. what profile you need to use is entirely depens on your data patterns, let say it has promation activities in past then we will use casual analysis model.

3. we have techniques in each profile like univarite - LR, SLR, Holts winters like and similarly you have MLR for causal analysis

4. there will error measures for univariate and causual but not for composire becuase composite is really not a techniq, it just an weigheted avg of both the models. if you want to use both univariate and MLR for the same data then run both of them take the avg of it like, the composite wil help you to take the avg or % of wighing.
