(5.31)

e 5.14 shows a Gamma density fitted to the smoothed peak

shown in Figure 5.13. It can be seen that the density shows a

d fit to the peak height histogram density.

The raw peak height density (in histogram) and the fitted Gamma density

r the smoothed peak spectrum shown in Figure 5.13.

The relationship between peak heights and p values derived from a Gamma

d to the peak heights for the smoothed peak spectrum shown in Figure 5.13. For

le, 19 p values were less than 0.01 corresponding to 19 peaks which were then

he true peaks due to their significantly low p values and hence significant greater

ts.

ugh fitting a Gamma density to the peak heights from a smoothed

ctrum, peaks with significantly great heights can be considered as

ficant peaks, i.e., potential signals. Based on an estimated Gamma
