The equation as is does not make sense. min(x) does not make sense since x is a number. Better to use something like this: http://www.dataminingblog.com/standardization-vs-normalization/ 2001:8A0:FF93:2B01:B4C8:FAB6:A9D:F736 (talk) 14:57, 6 September 2015 (UTC)

Rescaling formula does not do what it says
When subtracting the average value of x from the original value, you won't rescale the data between [0 1]. Also the example does not follow the formula.

Suspect formula for arbitary values is incorrect
Section ''to rescale a range between an arbitrary set of values [a, b], the formula becomes: ....... where a,b are the min-max values''

Formula I think should be min_a+(((x{i}-min_x)/(max_x-min_x))*(max_b-min_a)); 161.29.24.159 (talk) 02:53, 6 June 2024 (UTC)


 * Haha, on closer inspection same result just written a different way  so formula is correct :) 161.29.24.159 (talk) 02:59, 6 June 2024 (UTC)
