Hi guys,
I'm writing to ask for some reading suggestions for market share modelling (over time).
Just to give some context, we are talking about analyzing a set of variables *over time* that express the market share (so each of them is bounded to be 0<x<1 and their sum is equal to 1 by construction).
I'm pretty sure there is some literature out there, both to analyze these variables by themself and also to take into account other sets of variables.
