Description
Technical Field
The present invention relates to the field of data analysis, and in particular, to a system and method for adaptive multiplexing coding.
Background
Data analysis is the basis of a quality management hierarchy, where appropriate, the manager of the organization should evaluate its effectiveness by analysis of the following questions:
(1) Whether the information providing decision is sufficient and reliable or not, and whether the problem of decision error caused by insufficient information, misalignment and hysteresis exists or not;
(2) Whether the information is consistent with expected values for continuously improving the quality management system, the process and the effect exerted by the product or not, and whether data analysis is effectively applied in the product realization process or not;
(3) Whether the purpose of collecting data is clear, whether the collected data is real and full, and whether the information channel is smooth;
(4) Whether the data analysis method is reasonable or not, and whether the risk is controlled in an acceptable range or not;
(5) Whether the resources required by the data analysis are guaranteed or not.
Meanwhile, the data analysis has a very wide application range, and a typical data analysis may include the following three steps:
(1) Exploratory data analysis: when the data is just obtained, the data can be disordered and irregular, the regularity is not seen, and the possible forms of regularity are explored by means of drawing, tabulation, fitting by using equations of various forms, calculating certain characteristic quantities and the like, namely, what direction and in what way to find and reveal the regularity hidden in the data;
(2) Model selection analysis, namely providing one or more types of possible models on the basis of exploratory analysis, and then selecting a certain model from the models through further analysis;
(3) Inference analysis: mathematical statistical methods are typically used to infer the degree of reliability and accuracy of the model or estimate.
