The Stored Life Analysis System

The statistical expert system is a new research field in Statistics. It is the result of applying Artificial Intelligence in Statistics. The statistical expert system is also called intelligent statistical software. There are several popular statistical software, such as SAS, SPSS. These software have strong power in computing. But it is complained that these software are lack of flexibility and transparency. And for the users that are unfamiliar with the theory of Statistics it is easy to make a mistake in explaining and evaluating the data analysis results. So there is a voice for a more friendly and well explanation statistical software for a long time. The stored life analysis system is a general statistical software in analyzing ammo life status. It uses the knowledge of Economics, Ammo Engine and Computer Science. It is a platform of statistical analysis, and is mainly used to deal with the test data of ammo. It combines the experience of ammo experts and statistician. This helps it avoid producing the analysis reports which have right theoretic meaning but wrong actual meaning. The stored life analysis system can be used to analyze the test data of unit part and integration part. It gives the estimated parameters step by step and a completed data report finally. It also gives the necessary graphs and tables to help explaining the complex result into easy ones. It is preferred for the users who have little concept in Statistics. And it supplies the users to save the data report and re-edit them. In the arithmetic analysis aspect, the stored life analysis system refers not only to the traditional statistical method but also to the newly research results by the professors in Peking University and Beijing University of Technology. In the software research and development the stored life analysis system uses freedom software R. R is a free and source-code opened software, and is a part of GNU system. It is an easy-using software in Statistic Computing and Statistic graph. And users can add new toolbox in R, which can widen R in new methods of data analysis. The statistic analysis module is main analysis module in the stored life analysis system. Based on the characteristic of experiment data, statistic analysis module mainly deals with two kinds of data, which are simple part data and multi part data. It is divided into two kinds of flows in analysis procedure, which are manual intelligence analysis and automatic intelligence analysis. In manual intelligence analysis, there are several nodes in key steps of data analysis. In each node, users may choose different models or methods to do with data, and get different results in each branch. This helps users to get the optimum model of experiment data. In automatic intelligence analysis, the system uses each model to do with the experiment data. Users may choose an optimum one from them.
