STL decomposition is based on loess, the local weighted regression scatter smoothing method, which was 1990 by the University of Michigan's R. B. Professor Cleveland and W of Att Bell Laboratory. S. Cleveland a method of decomposing time series. The STL decomposition breaks down the time series into seasonal items, trend items and residues. In order to study this method, I spent a day poring over this paper, completed 17 pages of translation (original

In data analysis, we often encounter the problem of missing value. The general missing value of the processing method has the deletion method and the filling method. By deleting the method, we can delete the missing data samples or variables. The missing value filling method can be divided into single variable filling method and multivariable filling method, in which the single variable filling method can be divided into random filling method, median/median filling method, return filling method

, there is usually a difference between a text file and a binary file (binary files). But this difference is somewhat misleading, in fact, each computer file is composed of 0 and 1 encoding, in this sense, all files can be considered binary files. The text file is defined here as a file consisting primarily of ASCII characters or other human language encodings (such as GB encoding for Chinese), and the use of newline characters makes it feel that the file is made up of rows. A non-text file, suc

Social networking Analysis (social network ANALYSIS,SNA) has gradually become another favorite in the field of data mining. The essence of SNA is to analyze the community phenomenon of the whole sample by using the relationship between each sample (and therefore also become a relational network), and analyze the role of sample points in community formation and the relationship between communities. The SNA is implemented using the Igraph package in the R
