Ch. 16 Stochastic Model Building Unlike linear regression model which usually has an economic theoretic model built somewhere in economic literature, the time series analysis of a stochastic process needs the ability to relating a stationary ARMA model to real data. It is usually best achieved by a three-stage
wrong shape for a heavenly messenger. Anyway, it's time to stop wondering whether she came from heaven or a nearby town. What matters is this: whoever she was, Aunt Esther Gubbins was right.\
1. Strength and weakness of anthropology: Anthropologists are often swayed by a single key case a. Weakness in that this is an obviously inadequate sample. No way of knowing if typical or how typical b. Strength in that rich analysis, really can tell you a lot
Ch. 3 Estimation 1 The Nature of statistical Inference It is argued that it is important to develop a mathematical model purporting to provide a generalized description of the data generating process. A prob bility model in the form of the parametric family of the density functions p=f(:0),0E e and its various ramifications formulated in last chapter
Ethnography 1. INTRO Originally people who studied cultures were amateurs who happened to either be particularly observant or who happened to travel a lot. Some of them did more or less what people did today. a. Ibn Khaldun was a famous Arab scholar who did observations of everyone, including the Vikings
Ch. 22 Unit root in Vector Time series 1 Multivariate Wiener Processes and multivari- ate FCLT Section 2.1 of Chapter 21 described univariate standard Brownian motion W(r) as a scalar continuous-time process(W: rE0, 1-R). The variable W(r) has a N(O, r)distribution across realization, and for any given realization, w(r) is continuous function of the date r with independent increments. If a set of k such independent processes, denoted
