Abstract

PURPOSE:To recognize an analyzed result by Japanese by displaying the analyzed result by means of a statistic analysis part and a judged result by means of an analyzed result judgement part by means of combining them. CONSTITUTION:Input data 1 is data of a measured table system, and it is the set of data on a numeric value, a character and a code. A data input part 2 fetches a part required for analysis from input data 1, and transfers control to the statistic analysis part 3. The statistic analysis part 3 analyzes data based on a designated statistic method, and the analyzed result is outputted to which an identification index is added. The analyzed result judgement part 5 verifies whether the analyzed result is statistically correct or not based on information accumulated in a knowledge base 6, executes synthetic judgement and outputs judged result data 7. An editing/display part 8 combines analyzed result data 4 with judged result data 7, edits a layout so that a man can easy to view and displays display data 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a statistical analysis system, and more particularly to a statistical analysis control device.

[0002]

2. Description of the Related Art Conventionally, a statistical analysis control device, as shown in FIG. 4, outputs an analysis result as it is as a numerical value or displays it as a part of a graph, but it is entirely up to humans to make decisions. There is.

[0003]

The above-described conventional statistical analysis control device has the drawbacks that the display is difficult to understand and specialized statistical knowledge is required.

[0004]

A statistical analysis control device of the present invention comprises a data input section for inputting data, a statistical analysis section for performing data analysis based on a specified statistical method, and an analysis result by the statistical analysis section. Edit to display a combination of the analysis result judgment unit that statistically verifies the information based on the information accumulated in the knowledge base and makes a comprehensive judgment, and the analysis result by the statistical analysis unit and the judgment result by the analysis result judgment unit -A display unit is provided.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The input data 1 is the measured tabular data, which is a set of data such as numerical values, characters, and codes. The data input unit 2 takes in a portion required for analysis from the input data 1 and passes control to the statistical analysis unit 3. The statistical analysis unit 3 analyzes the data based on the designated statistical method as in the conventional case. The analysis result is output with the identification index added. The analysis result judging unit 5 verifies whether or not the analyzed result is statistically correct based on the information accumulated in the knowledge base 6, and makes a more comprehensive judgment based on the result. The judgment result data 7 is output. The editing / display unit 8 combines the analysis result data 4 and the judgment result data 7 to edit the layout so that it is easy for humans to see, and displays the final display data 9.

FIG. 2 shows an analysis result judging section 5 for checking and judging based on the information accumulated in the knowledge base 6.
It is a block diagram showing. The analysis result data 4 analyzed and output by the statistical analysis unit 3 is provided with an identification index. According to the identification index, first, the validity of the characteristics of the original data (for example, the size of the population, the deviation of the data, the presence / absence of an abnormal value, the cleaning of the data, etc.) is verified, and the data validity determining unit 51. Do in. Next, the variable independence determination unit 52 verifies the presence or absence of correlation between variables. Further, the model validity determining unit 53 verifies the validity of the model formula such as the regression model. Finally, in addition to the verification results of the determination units 51 to 53, the comprehensive determination unit 54 makes a comprehensive determination by also considering the information of the knowledge base 6 in which human empirical rules are added.

An example of execution is shown below based on specific data.

It is assumed that the data input through the data input unit 2 is as follows: Student number Mathematics Science Japanese English 1 70 85 75 75 70 2 90 95 60 60 80 3 40 50 90 70: :: :: :: :: :: : When analyzing the relationship between the results of "mathematics" and the results (scores) of "science", first, a simple regression analysis is performed in the statistical analysis unit 3, and standard statistics or regression coefficients with identification indexes are given. Create an ANOVA table, etc. Next, referring to the knowledge base 6, the deviation of the data and the abnormal value are checked from the data distribution and the standard deviation, and the validity of the data is checked (the validity judgment unit 51 of the data). Further, the independence of variables is checked from the correlation coefficient and its t-test result (variable independence determination unit 52), and the validity of the model formula is checked from the values of the variable factors in the analysis of variance table and the F-test results (model Validity determination section 53).

Finally, human verification rules accumulated in the knowledge base 6 in the verification results of the determination units 51 to 53 (eg, in the case of such data, it is desirable that the contribution rate is 0.8% or more). ) Is added to give a comprehensive judgment result (general judgment unit 54).

The overall judgment result is divided into the following four types: Significance level evaluation message 1% or less Significantly related 1-5% Significantly related 5-10% Somewhat related 10% or more Most Unrelated Japanese messages corresponding to each are edited / displayed 8
It is also combined with analysis data and displayed in an easy-to-understand manner.

FIG. 3 shows an example in which the analysis result of the semi-regression analysis and the result comprehensively judged by the analysis result judging unit 5 are displayed on the editing / display unit 8 in a form (graph, Japanese) which is easy for humans to understand. Indicates.

With this evaluation message and graph, it is possible to grasp at first glance the relationship between mathematics and the results of science.

[0014]

As described above, according to the present invention, the analysis result can be understood at a glance in Japanese by statistically making the necessary statistical judgment on the control device side with respect to the statistical analysis result. The effect is that it can be used even without.
