Exercise

Examine skewness from contour plot

In this exercise, we will examine the contour plot of a pair of variables to decide whether to go beyond symmetric distributions like normal and t-distributions and use a skew-normal distribution to model a dataset.

Examine the contour plot of the variables Ht and Wt from the ais.female dataset, which contains the observations from the female athletes of the Australian Institute of Sport data. Which of the following distribution types best describe the data?
