Xlstat association rules series#
Series before and after transformation: This table displays the series before and after transformation. By the use of a normality test, you can verify these premises (see the Normality Tests in XLSTAT-Pro).Results for subgroup charts in XLSTATBox-Cox transformationĮstimates of the parameters of the model: This table is available only if the Lambda parameter has been optimized. Note: During the interpretation of the different indicators for the process capability please pay attention to the fact that some indicators suppose normality or at least symmetry of the distribution of the measured values. The S chart draws the standard deviation of the process and the S’² chart draws the variance (which is the square of the standard deviation). S and S’² charts are also used to analyze the variability of production.A large difference in production, caused for example by the use of different production lines, will be easily visible. An R chart (Range chart) is useful to analyze the variability of the production.Mean shifts are easily visible in the diagrams. An X bar chart is useful to follow the mean of a production process.The subgroup charts tool offers you the following chart types alone or in combination: Integrated in this tool, you will find Box-Cox transformations, calculation of process capability and the application of rules for special causes and Westgard rules (an alternative set of rules to identify special causes) to complete your analysis. This tool is useful to recap the mean and the variability of the measured production quality.Subgroup chart in XLSTAT The measurements need to be quantitative data. It is used to supervise production quality, in the case where you have a group of measurements for each point in time.
Subgroup ChartsWhat is a subgroup control chartĪ subgroup chart is a type of control chart that focus on the quality characteristic measurement within one subgroup. The bottom line is that XLStat offers a wide range of features to users of any level of experience.XLSTAT 는 MS 엑셀에서 통계처리를 할 수 있도록 개발된 프로그램입니다. It did not cause Microsoft Excel to hang, crash or pop up error dialogs during our tests. The Excel add-on runs on a low amount of CPU and system memory, so it doesn’t interfere with the runtime or other currently active processes. A versatile Excel add-in for running statistical analysis DataFlagger, sheet management, export to graphics) and utilities regarding CJT, Time, SIM, SPC, DOE, Life, ADA, PLS PM, and Dose. Mantel, Cochran-Armitage, K proportions, McNemar), as well as use various tools (e.g. Moreover, you may run correlation/association, parametric and nonparametric tests (e.g. In other words, not only that you have modeling and analysis tools at your disposal, but you can also use the models and rules of XLStat for machine learning. factor or discriminant analysis, k-means clustering) and to model it via distribution fitting, linear regression, mixed models and logistic regression, just to name a few. Additional features of XLStat allow you to analyze information (e.g.
