A mathematical error
In page 18, the equation
is transformed by taking the logarithm of both sides, the authors say
ln y=-kt+lnA'+ln(mt+b) (2.23)
This is wrong!
17=10+7 but, ln 17 is NOT equal to ln 10 + ln 7.
In page 17, a very important point about linearizing the nonlinear data is mentioned. A weighted lease-squares is needed in logarithmic transformation.
But, in many actual applications, HPLC method is used. In such data, the noise (error) is expressed as coefficient of variation, not a constant variance.
In this case, weighting is not really needed. A practical aspect like this has to be explored in more details.
This book however has collected many topics in chemical data analysis from literatures, and can be a good reference in many disciplines.
