Description: Data for 2 experiments relating growth (number of colonies)
of salmonella to dose. Model fit was:
Y = (b0+exp(b1+b2*ln(X)))*exp(-b3*X)
The second data set displays heteroskedasticity and can be fit by EWLS
X=0 is replaed with X=0.000001
Variables/Columns
Experiment (Day) 8
Dose 10-16
Yield 20-24
