Web3 dec. 2016 · How to run a regression on a subset in R Sometimes we need to run a regression analysis on a subset or sub-sample. That’s quite simple to do in R. All we need is the subset command. Let’s look at a linear regression: lm (y ~ x + z, data=myData) WebOkay, now let’s redraw our pictures, but this time I’ll add some lines to show the size of the residual for all observations. When the regression line is good, our residuals (the lengths of the solid black lines) all look pretty small, as shown in Figure 15.4, but when the regression line is a bad one, the residuals are a lot larger, as you can see from looking at Figure 15.5.
