Thank you to Chenliang Wang for presenting Geographically Weighted Regression (GWR) analysis of spatial data at the MADlib community meeting.
Here are some follow up questions that we did not get to in the meeting. Chenliang, could you briefly respond? 1) what type of matrix operations are required? 2) how will the algorithm be parallelized? 3) is raster support for PostGIS a requirement? (GPDB currently does not support as per http://gpdb.docs.pivotal.io/4340/ref_guide/postGIS.html#topic_wy2_rkb_3p) 4) what does the 160 refer to in your slides? Thanks again, Frank
