Quantification of Uncertainty in Mathematical Models: The Statistical Relationship between Field and Laboratory pH Measurements

Figure 4

(a) Linear model (original data) for field versus with least-squares minimisation and 95% CI (narrow band) and 95% PI (broad band). Note the degree of variation possible at different pH levels (cf. Figure 3, Steinhardt and Mengel [13])
