JMP for Mixed Models

Chapter 6Repeated Measures and Longitudinal Data

In this chapter, we examine experiment designs that require repeatedly measuring the same experimental units, whether by taking many different types of measurements on the same unit or taking repeated measurements of the same type, over time, on the same unit. When you take repeated measurements, these repeated observations are no longer independent of each other.

With repeated measures analyses, we will still answer the standard mixed model questions about which treatment and experiment design factors demonstrate statistically significant relationships to the response and where those differences lie. However, the special feature in this type of repeated measures analysis is that we must include ...
