Exercise

Plotting data and linear model fit

In the previous exercises you have practiced how to fit and interpret the Poisson regression model. In this exercise you will visually analyze the crab data and then the model fit.

First, you will plot a linear fit to the data, which later on you will use to compare to Poisson regression fitted values.

Instructions

100 XP
  • Import seaborn and matplotlib libraries.
  • Using crab dataset plot the data points with width on the x-axis and sat on the y-axis, with jitter of 0.3 for the sat variable.
  • Add a linear model fit by setting the argument fit_reg to True.
  • Set 'color' of the line fit as 'green' and the 'label' as 'LM fit'.
