The collected data were analyzed using IBM SPSS Statistics v 14 (SPSS Institute; The IBM Corporation, Somers, NY). Statistical tests included descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient and multiple linear regression. P values less than 0.05 were considered statistically significant.
When writing parallel computing code, a Reduce operation allows you to compute statistics on a large amount of inputs. In Earth Engine, you need to run reduction operation when creating composites, calculating statistics, doing regression analysis etc. The Earth Engine API comes with a large number of built-in reducer functions (such as ee.Reducer.sum(), ee.Reducer.histogram(), ee.Reducer.linearFit() etc.) that can perform a variety of statistical operations on input data. You can run reducers using the reduce() function. Earth Engine supports running reducers on all data structures that can hold multiple values, such as Images (reducers run on different bands), ImageCollection, FeatureCollection, List, Dictionary etc. The script below introduces basic concepts related to reducers.
