The hypothesis test of statistics can be divided into parameter test and nonparametric test, the parameter test is calculated according to some assumptions, when these assumptions can not be satisfied, the efficiency of the parameter test will be greatly discounted, even the wrong result, and the non-parameter test is usually without the hypothesis condition, so the application scope is wider than the parameter test.Non-parametric testing in the case of no assumptions, the maximum use of sample

related indexes to collect the data required by the CBO.
The CBO is the recommended optimization method for Oracle, and the timeliness of the statistics must be ensured in order to use a good CBO to maximize the effectiveness of the SQL statements.
The statistical information can be generated by the method of complete calculation and sampling estimation. The SQL examples are as follows:

If the groups are not independent (such as repetitive measurement designs or random block designs), then the Friedman test will be more appropriate. The invocation format for the Kruskal–wallis test is:Kruskal.test (y~a,data) where y is a numeric result va

, but definitely not exceeding (n + 1), then the number of times each I appears, that is, the remainder of a [I] pair (n + 1.
There is also a method of traversing twice, which is also the above idea: consider a [I], the current position is I, if you use a to count, its position should be a [I] % (n + 1). How can I handle this position when finding the counting position? Add 1? Obviously not. Here is a trick, that is, adding (n + 1) for two reasons.
Adding N ensures that a [I] % (n + 1) remains
