The objective of the Assignment is as follows: 1) Calibrating a simple linear regression to reveal the relation between public bus commuters’ flows (i.e. tap-in or tap-out) data and residential population at the planning sub-zone level. 2) Performing spatial autocorrelation analysis on the residual of the regression model to test if the model conforms to the randomization assumption. 3) Performing localized geospatial statistics analysis by using commuters’ tap-in and tap-out data to identify geographical clustering.
