Correlation analysis possible outcomes from

Figure 5. Possible outcomes from correlation analysis (a) r = 0, negative linear relationship (b) r = 0 positive linear relationship (c) r = 0, no linear relationship (d)r = 0, X and Y are related but not linearly.

Another important criterion for Raman microspectroscopic analysis is the selection of the areas to be analyzed, as this offers the possibility to directly correlate the spectroscopically determined outcomes with results from other techniques such as histology/histomorphometry [200]. In addition, most of the samples from clinical or animal studies are in most cases labeled with...
