Saturday, May 16, 2020 / pdf

6.2 Graphing Lines by Intercepts Let’s start with graphing a couple more lines using a table of values. We will use these to make some observations. Example1: Graph. a. y = 5x – 3 b. y = -2x + 4 Solution: a. We will use a table of values as we did in the previous section, however, we will only use three points, x = -1, 0, and 1, since three points will provide a sufficient amount of data …

### Random Intercept and Random Slope Models

Saturday, March 28, 2020 / pdf

School effects (intercepts) are random. The effects of the intake variable (slopes) are random and differ between schools. This implies that both the intercepts and slopes for each school are ‘shrunk’ towards the overall average line. Here have σ2 u0 = 0.090 (variance of school intercepts) and σ 2 u1 = 0.015 (variance of school slopes).
