— This image just caught my eye because of the yellows.

The next posts will build through:

1. A consideration of linear regression ideas;

2. Linear regression steps in R;

3. The groundwork for an extension of regression to mixed-effects modelling;

4. Mixed-effects modelling in R.

I will return to some steps repeatedly over time.
