Estimation

Once we have confirmed that our sample satisfies the conditions for inference, we can use the results in three estimation contexts. This section explains the three common ways that regression results can be used and introduces ways to use JMP in all three contexts.

  • In some studies, the goal is to estimate the magnitude and direction of the linear relationship between X and Y, or the magnitude of the intercept, or both.

  • In some situations, the goal is to estimate the mean value of Y corresponding to a particular value of X.

  • In some situations, the goal is to estimate an individual value of Y corresponding to a particular value of X.

Earlier, we estimated this regression line based on our simple random sample:

If we had drawn a different ...
