Example 6

The dataset contains optical density of microtubes with Staphylococcus aures ("OD"), which was cultivated in the media with different pH ("pH") and different concentrations of glucose, % ("Glucose"). The experiment was designed in order to evaluate influence of pH and glucose concentration on the growth of S. aureus. This example is disccused in Regression analysis.
