Evaluating data from bioreactors

Let us perform the procedure using the data from Example 4.2 (Table 4.10). This was an evaluation using six x,- variables in predicting the total amount of growth medium for a continuous bioreactor—biofilm—process. The researcher ranked the predictor values in the order of perceived value Xj, temperature (°C) X2 logio microbial count per cm coupon X3, medium concentration X4, calcium/phosphorous ratio X5, nitrogen level, and Xg, heavy metals. 

The following product quality data were obtained from a bioreactor, based on a photometric measurement evaluation of the product ...
