For a given data set X of 3 - D samples,

(a) fi nd the outliers using the distance - based technique if (i) the threshold distance is 4, and threshold fraction p for non - neighbor samples is 3, and (ii) the threshold distance is 6, and threshold fraction p for non - neighbor samples is 2.

(b) Describe the procedure and interpret the results of outlier detection based on mean values and variances for each dimension separately.
