P value with xlstat series#
Time series smoothing including exponential and moving average. Simple and multiple linear regression with many options including weights, 2-way interactions, validation procedures, predictions, multicollinearity statistics, missing data handling and type III effects.ġ-way and 2-way ANOVA for balanced or unbalanced data, with many options including weights, 2-way interactions, validation procedures, predictions, missing data handling and type III effects.

Cette approximation est d’autant plus fiable que le nombre de blocs et/ou de traitements est important. Paired and independent 2-sample t-tests and z-tests, including one-tailed and two-tailed alternative hypotheses.Ģ-sample non-parametric tests (Wilcoxon’s test, sign test, Mann-Whitney’s test), including asymptotic, Monte Carlo and exact p-value computations. Pour le calcul de la p-value associée aux différentes statistiques, XLSTAT propose deux alternatives : - Méthode asymptotique : la p-value est obtenue grâce à l’approximation par la statistique qui suit une loi normale standard. It will work only when you have installed MS Excel.ĭescriptive statistics including several charts (pie charts, bar charts, box plots…)Ĭovariance and correlation analysis including Pearson, Spearman and Kendall correlation coefficients, correlation maps, scatter plot matrices and many more. You will need a laptop with XLSTAT loaded, or you can hire a machine for the day for an additional small fee.XLSTAT is an data analysis tool using Microsoft Excel as a backend. Performing Breusch-Pagan and White heteroscedasticity tests in XLSTAT Open the XLSTAT menu and click on Time / Tests for heteroscedasticity. There is plenty of opportunity for practice using XLSTAT through “hands on exercises” for which annotated solutions are provided. Therefore, if the p-value associated to a heteroscedasticity test falls below a certain threshold (0.05 for example), we would conclude that the data is significantly heteroscedastic. It also serves as a useful refresher course to those who once studied statistics as part of a college course. After you have clicked on the OK button, the results are displayed on a new Excel sheet (because the Sheet option has been selected for outputs). Note that exact p-value can be computed with XLSTAT. No previous knowledge of statistics is necessary with this course, as we start right from the beginning. In the options tab, we suppose that the difference between samples is equal to 0. We aim to explain the objectives of the techniques and to send you away with a better understanding of which technique to use when. The biopesticide treatments significantly (P Tithonia diversifolia could be a hopeful ecoresponsible solution for the plantain sector in general and in. Mathematical details are kept to a necessary minimum and we focus on the interpretation of the outputs from XLSTAT and illustrate applications with case studies using data from surveys, instrumental analysis, manufacturing processes, clinical trials and biological data. This course ensures that these concepts are understood in a non-technical way and then practised using real data examples.

There are many basic concepts that need to be understood before statistics can be used to its full potential to give useful and informative answers. This basic but wide-ranging course covers the easy to use features in XLSTAT for investigating, visualising and performing basic statistical techniques on data sets typical to research and industry settings.
