All applications are developed with R and Shiny.
Some applications will ask you to copy and paste data from excel, others to upload files in csv format.
In your csv file, data must be separated by commas and the decimals indicated with dot. Check it. 
For problems use the Forum 

Your data are uploaded and analyzed. After analysis they are discarded. During the analysis and after the analysis they are not displayed, they are not stored and they can not be used by any other user or administrator

A chi-squared test, also written as χ2 test, is any statistical hypothesis test where the sampling distribution of the test statistic is a chi-squared distribution when the null hypothesis is true.  The chi-squared test is used to determine whether there is a significant difference between the expected frequencies and the observed frequencies in one or more categories

Nonparametric statistics is the branch of statistics that is not based solely on parametrized families of probability distributions. Nonparametric statistics is based on either being distribution-free or having a specified distribution but with the distribution's parameters unspecified. Nonparametric statistics includes both descriptive statistics and statistical inference.

  • Mann-Whitney U-test

  • Wilcoxon signed-rank test

  • Kruskal-Wallis test

  • Friedman test

Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among group means in a sample. In its simplest form, ANOVA provides a statistical test of whether the population means of several groups are equal, and therefore generalizes the t-test to more than two groups. ANOVA is useful for comparing (testing) three or more group means for statistical significance.

The general purpose of multiple regression (the term was first used by Pearson, 1908) is to learn more about the relationship between several independent or predictor variables and a dependent or criterion variable.

  • Multiple Linear Regression

  • Multiple Logistic regression

Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. PCA is mostly used as a tool in exploratory data analysis and for making predictive models

Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense) to each other than to those in other groups (clusters). It is a main task of exploratory data mining, and a common technique for statistical data analysis

Survival analysis is a branch of statistics for analyzing the expected duration of time until one or more events happen, such as death in biological organisms and failure in mechanical systems.

Meta-analysis is a quantitative, formal, epidemiological study design used to systematically assess previous research studies to derive conclusions about that body of research. Outcomes from a meta-analysis may include a more precise estimate of the effect of treatment or risk factor for disease, or other outcomes, than any individual study contributing to the pooled analysis

Structural equation modeling (SEM) is a form of causal modeling that includes a diverse set of mathematical models, computer algorithms, and statistical methods that fit networks of constructs to data.

A scatter plot can be used either when one continuous variable that is under the control of the experimenter and the other depends on it or when both continuous variables are independent.

Statistical power is a fundamental consideration when designing research experiments. It goes hand-in-hand with sample size. The formulas that our calculators use come from clinical trials, epidemiology, pharmacology, earth sciences, psychology, survey sampling ... basically every scientific discipline.

Machine learning (ML) is a category of algorithm that allows software applications to become more accurate in predicting outcomes without being explicitly programmed. The basic premise of machine learning is to build algorithms that can receive input data and use statistical analysis to predict an output while updating outputs as new data becomes available.

A heat map (or heatmap) is a graphical representation of data where the individual values contained in a matrix are represented as colors

This shiny app can help the users to compare different smoothing models in forecasting, namely simple exponential smoothing, linear exponential smoothing and Holt-Winter method. Users can set the confidence interval and forecasting horizon by themselves. Also, users can choose to put in their own model parameters and see the difference between same model with different sets of parameters. The demo data set in app is “airpass” data set inserted in R package “fma”, you can also choose to upload your own data set.
