Average probabilities were calculated by creating 100 separate models, and then averaging the predicted probabilities in each pixel across the models. Lower probabilities (closer to 0%) indicate a substrate type is less likely to be present. Higher probabilities (closer to 100%) indicate a substrate type is more likely to be present. </SPAN></P><P /><P STYLE="margin:0 0 0 0;"><SPAN>The coefficient of variation (CoV) layers denotes the variation in the predicted probability of occurrence for each substrate type. CoV is unitless and is the ratio of the standard deviation to the mean for each pixel. It was calculated by creating 100 separate models, and then calculating the mean and standard deviation of probability of occurrence in each pixel across the models. For example, if in a pixel, the mean probability is 0.5 and the CoV is 0.1, then 0.5 × 0.1 = ±0.05 or ± one SD). Assuming normally distributed errors, 68.3% of the data will fall between ±0.05 (or 1 SD), 95.5% of the data will fall between ±0.1 (or 2 SD), and 99.7% of the data will fall between ±0.15 (or 3 SD).</SPAN></P></DIV></DIV></DIV> |
