    Comparing subsets of a population with a very different size (power law case)?

    My population (12000 data) is characterized by events that are either of type A or of type B. My goal is to figure out whether the relative proportion of A with respect to B does change if a property of the events (the size in my case) change. My first approach was quite simple: dividing the...

    multiple regression with power law relationship [help!!!]

    I am trying to carry out multiple regression of a dependent variable (DV)with 2 independent variables (IV1 & IV2) that exhibit power law relationship with the DV. i.e. DV = a*IV1^b and also DV = c*IV2^d where a,b,c,d are the coefficients of the power law relationships When I plot...

My fundamental question is how do I determine whether a given dataset is better fit by a linear model or a power law model? This...
