Refer to the use of linear discriminant analysis by R.A. Fisher in 1936 for Iris flower data, as discussed in the article “Iris flower data set” at Wikipedia. Conduct a linear discriminant analysis using the data given there for the versicolor and virginica species (which are in the Iris data file at the text website), with sepal length and petal length as explanatory variables. Report the linear discriminant function. Show the leave-one-out cross-validated classification table for π0 = 0.50.
