The dataset AVLTIME_NLREG.txt is to be fitted to the function Y = A * X + B. First, the data will be checked for outliers that should be rejected because they fall outside the "Prediction Band, PB" at a 95.4% confidence level. If any such points exist, a new dataset will be created, preserving the original data and excluding the points that fall outside the PB.
AVLTIME_NLREG.txt has 48 points. Point number 48 falls outside the "Prediction Band" (at a 95.4% confidence level). Therefore, it must be discarded, as will be shown in the following.
