True positive rate
Variable Definition
True positive rate is defined as probability of overlap between urban HSR and urban GUF pixels (the dataset used to derive the cross-sectional urban patch metrics) relative to GUF urban. In other words, it is the probability that the pixels classified as urban according to HSR are also classified as urban according to GUF. The measure was computed using the 2015 data. The true positive rate varies from 0 to 100. Missing values occurred for units that did not have negatives, false positives, true positives, or true negatives (because of missing data, for example) and which had zeroes in the numerator or denominator when computing the rates. Interpretation: Higher values mean greater agreement between HSR and GUF regarding urban pixels.
