The Assistant tool provides us with two methods of regression and a response optimizer for multiple regression. As with all the assistant tools, guidance is offered on the setup of the study and on the output. There are less options to choose from but the dialog box is simpler to use.

Here, we will use the Assistant tool to run a fitted line plot and then pick between Linear, Quadratic, and Cubic models for data on Hubble's constant.

Hubble's law describes the relationship between the distance of a galaxy and the velocity at which it is moving away from us. The greater the distance, the greater the velocity of recession. The data comes from observations on recession velocity of Nebula and its distance from the Earth.
