In the above graph draw relationship between size (x-axis) and total-bill (y-axis). Yet some binning is happening here: import pandas as pd import matplotlib. As we know from pre-calculus, b is the intercept with y axis and a1; a2; a3 are the values that will set the line slope. If the linear regression model is perfect, the predicted values will exactly equal the observed values and all the data points in a predicted versus actual scatterplot will fall on the 45° diagonal. import numpy as np import pandas as pd import seaborn as sns df = pd. Now, the scatter plot makes more sense. In this final section, we will explore seaborn and see how efficient it is to create regression lines and fits using this library!
