Produce a test report with improvement recommendations on a series of R scripts. The scripts and the test data are in the zip files attached. The data is in a CSV file with 7 columns (X1, X2, X3, X4, X5, Y1, Y2). The R scripts forecast Y1 and Y2 based on (X1..X5) using local linear regressions with Gaussian kernels via the npreg method in the np package.
The deliverable of this task is a test report with improvement recommendations. If we like the report, you'll be hired to implement your recommendations.
