This function implements the outlier detection algorithm using standard deviation and mean
Usage
z_score_method(data, d, learn)
Value
Numeric vector containing the indices of detected outliers.
Arguments
data
Input Data that will be processed with or without the tutorial mode activated
d
Degree of outlier or distance at which an event is considered an outlier
learn
if TRUE the tutorial mode is activated (the algorithm will include an explanation detailing the theory behind the outlier detection algorithm and a step by step explanation of how is the data processed to obtain the outliers following the theory mentioned earlier)
