Feature Scaling

Uncover hidden insights in your data with these 4 methods for smoothing a line. From rolling windows to spline interpolation, we'll reveal the secrets you need to know to unlock the full potential of your data.

Sometimes you need to compare features before using it for your linear models. A necessary transformation comes when the features are not equal in terms of magnitude. There exist many transformations * log transform * min-max scaling * power transform And another transform which uses z-scores. What are z-scores ? According to the booktext definition a zscore is The distance (standard dev) from which our value is to the mean. e.g. A given height : 159 and our sample pop has Mean (mu)
