Data Science How do you find line of best fit for a 3d model in Python? I have a dataframe with columns x, y, and z. The values create a polynomial scatterplot. I used polynomialfeatures and fit to transform the data. I also did linear regression on the values per teachers instructions. I am not sure if it is correct since there are three axes instead of planar. When I try to make z-test data from x-test and y-test, I can't get the code to work. I am not sure what I am doing wrong. I really need some direction. # Plot Curve Fitx_test = np.linspace(-21,21,1000)y_test = x_test z_test= model.predict(x_test.reshape(-1,1))

0 A ladder tournament L can be split into two separate ladder tournaments L and L byassigning each player either to L or to L. The new ranks of the players are adjustedso that they do not contradict the relative rankings in L. However, there are manyways to define the inverse operation, joining two tournaments of disjoint players.Design algorithm Join-Ladder-Tournaments(L, L) that gives both tournamentsan equal value. This means, for example, that the joining does not force the championof L to compete against the worst players in L before she can have a match withthe champion of L
