In particular, how the conditional distribution evolves over time. In finance, different distributional specifications lead to different theories. For instance, one version of the random-walk hypothesis is that the conditional distribution F(rit|ri,t−1,…,ri1) is equal to the marginal distribution F(rit). In this case, returns are temporally independent and, hence, not predictable. It is customary to treat asset returns as continuous random variables, especially for index returns or stock returns calculated at a low frequency, and use their probability density functions.

2. 18 a Returns are in percentages and the sample period ends on December 31, 2003. The statistics are defined in eqs. 13).

14) is too general to be of practical value. However, it provides a general framework with respect to which an econometric model for asset returns rit can be put in a proper perspective. , the distribution of {r1t,…,rNt}). , the distribution of {ri1,…,riT} for a given asset i). In this book, we focus on both. In the univariate analysis of Chapters 2–7, our main concern is the joint distribution of for asset i. To this end, it is useful to partition the joint distribution as where, for simplicity, the parameter θ is omitted.
