WebMay 28, 2024 · Normalization (Min-Max Scalar) : In this approach, the data is scaled to a fixed range — usually 0 to 1. In contrast to standardization, the cost of having this bounded range is that we will end up with smaller standard deviations, which can suppress the effect of outliers. Thus MinMax Scalar is sensitive to outliers. WebJun 5, 2012 · One thing that people sometimes say is that if you have standardized your variables first, you can then interpret the betas as measures of importance. For instance, if β 1 = .6, and β 2 = .3, then the first explanatory variable is twice as important as the second. While this idea is appealing, unfortunately, it is not valid.
