Web29 de fev. de 2024 · 1 Answer. Normalization typically seeks to produce data with a mean of 0 and a standard deviation of 1, so we transform each data point x i by z i = ( x i − x ¯) / s. This will guarantee that the transformed Z variable has a mean of 0 and standard deviation of 1, except for (maybe) some numerical issues on a computer. WebA robust measure of scale is the median absolute deviation (MAD) given by the median of all absolute distances from the sample median: (1) The constant 1.483 is a correction factor that makes the MAD unbiased at the normal distribution.
