candle.data_utils.impute_and_scale_array(mat, scaling=None)

Impute missing values with mean and scale data included in numpy array.

Parameters:

• mat (numpy array) – Array to scale

• scaling (string) – String describing type of scaling to apply. Options recognized: ‘maxabs’, ‘minmax’, ‘std’. ‘maxabs’ : scales data to range [-1 to 1]. ‘minmax’ : scales data to range [-1 to 1]. ‘std’ : scales data to normal variable with mean 0 and standard deviation 1. (Default: None, no scaling).

Return type:

Returns the numpy array imputed with the mean value of the column and scaled by the method specified. If no scaling method is specified, it returns the imputed numpy array.
