Solved: The file flow-occ contains data collected by loop
Chapter , Problem 49(choose chapter or problem)
The file flow-occ contains data collected by loop detectors in all three lanes (see Section 14.7). Examine the relationship of flow in lane 3 versus that in lane 1. Make a scatterplot and fit a regression line. Does the linear relationship look accurate or is there some systematic misfit? Fit local linear relationships with several bandwidths. Identify a bandwidth that is too small and one that is too large. What bandwidth appears to provide a good balance between being too wiggly and being over-smooth?
