Scaling Datasets
For best results, try scaling your data sets. Imagine a data set with x values ranging from -10 000 to 100 000 and a regression model where the term 2^x is involved. The calculation will overflow because 2^100000, and the regression will fail as a result. Therefore ndCurveMaster cannot use 2^x formula in this case.
If data set looks like this:
X = [-10 000, -5 000, 0, 500, 1000 ,10 000, 100 000] metres, you can scale this data to the following data set:
X = [-10, -5, 0, 0.5, 1, 10, 100] kilometres.
