Exercise  Linear Discriminant AnalysisSuppose you are the manager of a bank and you have the problem of discriminating between genuine and counterfeit banknotes. On the left you see a banknote worth 1000 Austrian schillings (about 72.67 Euro). You are measuring several distances on the banknote and the width and height of it. Measuring these values of about 100 genuine and 100 counterfeit banknotes, you will finally end up with a table of 200 observations with several variables. Use the data set FLURIEDW to
set up a model which is based on linear discriminant analysis and is capable
of discriminating between genuine and counterfeit money (this data set
contains data on Swiss francs; it has been obtained courtesy of H. Riedwyl
[Flury 1983]). Use DataLab
to calculate the model.
Use the calculated model to find out which of the following bank notes are counterfeit: Length Left Right Bottom Top Diagonal
