Implement standardize method (center + scale) #11

Open tk3369 opened 3 years ago

Standardization is a basic technique to transform data to have mean = 0, standard deviation = 1.

While this is listed as one of the normalization methods, it does not really make any material changes to the distribution of data i.e. the result does not become more "normal" than before.

See https://github.com/petersonR/bestNormalize/blob/master/R/no_transform.R#L113

I have second thought about this. Perhaps we should just exclude this method since it doesn't really normalize. But I'm in favor of doing #16.
