Ever wonder what sorts of errors freshman math students make? There are a couple of pretty basic ones.

I displayed these d values on the graph for you. Notice that they are the vertical distance from the real data points to the fitting linear function. Why this way?

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.

Asymptotic expansions of the distributions of the linear and the quadratic discriminant functions are derived. The expected misclassification probabilities of these two functions are compared when the ...
