RMD 7 will primarily include notes on correlated data from our session with Dr. Macnamara. This will be a short RMD.
“Correlated data is encountered in nearly every field. In education, student scores from a particular teacher are typically more similar than scores of other students who have had a different teacher. During a study measuring depression indices weekly over the course of a month, we usually find that four measures for the same patient tend to be more similar than depression indices from other patients. In political polling, opinions from members of the same household are usually more similar than opinions of members from other randomly selected households. The structure of these data sets suggest inherent patterns of similarities or correlation among outcomes. This kind of correlation specifically concerns correlation of observations within the same teacher or patient or household and is referred to as intraclass correlation.”

We will have both fixed and random effects.
