MULTILEVEL ANALYSIS

2. Multilevel data and multilevel analysis 11{12 Multilevel analysis is a suitable approach to take into account the social contexts as well as the individual respondents or subjects. The hierarchical linear model is a type of regression analysis for multilevel data where the dependent variable is at the lowest level.

Chapter 4 RANDOM VARIABLES - University of Kent

behaviour of a (discrete) random variable. In practice we often want a more concise description of its behaviour. DEFINITION: The mean or expectation of a discrete rv X, E(X), is defined as E(X) = X x xPr(X = x). Note: Here (and later) the notation X x means the sum over all values x in the range of X. The expectation E(X) is a weighted ...

2.2 Two variables Consider now two random variables X,Y jointly distributed according to the p.m.f p(x,y). We now define the following two quantities. Definition The joint entropy is given by H(X,Y) = − X x,y p(x,y)logp(x,y). (4) The joint entropy measures how much uncertainty there is in the two random variables X and Y taken together.

Again, this will be discussed more fully below, but the basic idea is that the xed e ects parameters tell how population means di er between any set of treatments, while the random e ect parameters represent the general variability among subjects or other units.
