Covariance plays an important role in Signal Analysis:1. It indicates whether X is positively correlated or negatively correlated with Y. If X is negative, the covariance is positive and the covariance is positive. 2. Covariance shows the correlation degree of X and Y. When the correlation points are scattered in the four quadrants, the correlation degree is very low. When the correlation points are distributed on the average line of X and Y, indicates unrelated. When the correlation point is cl

Secondary slice

For example, a list is defined as follows:

Also note that the type of the input and output must be consistent with the declaration in the custom reducer.22 orders are sorted first by first field, then the same row in the first field is sorted by the second field, note that the result of the first sort cannot be broken. For exampleInput file20 2150 5150 5250 5350 5460 5160 5360 5260 5660 5770 5860 6170 5470 5570 5670 5770 581 23 45 67 82203 2150 51250 52250 53530
. setgroupingcomparatorclass. As long as the two keys compared by this comparator are the same, they belong to the same group and their values are placed in a value iterator, the iterator uses the first key of all keys in the same group. Finally, it enters the reduce method of CER Cer. The input of the reduce method is all (key and Its Value iterator ). Also note that the input and output types must be consistent with those declared in the Custom CER Cer.
