Abstract

The invention belongs to the technical field of mathematical calculation, and discloses a sample overall covariance judgment method and device, equipment and a storage medium. The method comprises thesteps of obtaining sample clusters contained in a to-be-discriminated sample and sample index numbers corresponding to the sample clusters; detecting whether the sample index numbers are consistent or not; if so, acquiring a sample detection statistical observation value corresponding to each sample population; judging whether the sample detection statistical observation value is smaller than a preset critical value or not; and when the sample detection statistical observation value is smaller than the preset critical value, judging that the total covariance corresponding to each sample is equal. Through the above mode, the sample discrimination efficiency and accuracy are improved under the condition that the user discriminates the overall covariance equivalence of the sample and the time is saved.

Description

technical field [0001] The invention relates to the technical field of mathematical computing, and in particular, to a method, device, equipment and storage medium for determining the covariance of a sample population. Background technique [0002] In recent years, massive data has brought huge amount of information to users, and it has also brought great challenges to the analysis methods of data samples. When analyzing data samples in the existing technology, many theories and methods are based on the premise of large samples, but these Theories and methods cannot quickly classify these large amounts of high-dimensional data. For example, human genetic data often contains hundreds of thousands or millions of genetic variables, but traditional statistical analysis methods take into account the situation when the capacity of genetic variables is large. , it is difficult to quickly and accurately classify genetic variable data samples. Therefore, there is an urgent need for a...
