BlueSky Statistics is a free and open-source graphical user interface for the powerful R language. There is also a commercial “Pro” version that offers tech support, priority feature requests, and many powerful additional features. The Pro version has been beefed up considerably with the new features below. These features apply to quality control, general statistics, team collaboration, project management, and scripting. Many are focused on quality control and Six Sigma as a result of requests from organizations migrating from Minitab and JMP. However, both versions of BlueSky Statistics offer a wide range of statistical, graphical, and machine-learning methods.

The free version saves every step of the analysis for full reproducibility. However, repeating the analysis is a step-by-step process. The Pro version can now rerun the entire set at once, substituting other datasets when needed.

You can obtain either version at https://BlueSkyStatistics.com. A detailed review is available at https://r4stats.com/articles/software-reviews/bluesky/. If you plan to attend the Joint Statistical Meetings (JSM) in Portland next week, stop by Booth 406 to get a demonstration. We hope to see you there!

Copy and Paste data from Excel

      Copy data from Excel and paste it into the BlueSky Statistics data grid. This is in addition to the existing mechanism of bringing data through file import for various file formats into BlueSky Statistics to perform data analysis.

      Undo/Redo data grid edits

      Single-item and muti-items data element edits can be discarded by undo and restored by redo operations.

      Project save/open to save/open all work (all open datasets and output analysis)

      Analysis performed can be saved into one or more projects. Each project contains all the datasets along with all the analyses and any R code from the editor. The projects can be exported and shared (sent as .bsp, which is a zip file; “bsp” is an abbreviation of BlueSky Statistics Project) with other BlueSky Statistics users. The users can import projects, see all the datasets and analyses stored in the projects, and subsequently add/modify/rerun all the analyses.

      Enhanced cleaning/adjustment of copied/imported Excel/CSV data on the Datagrid

      Dataset > Excel Cleanup

      There are a few enhancements made to offer additional data cleanup/adjustment options to the existing Excel Cleanup dialog to clean/adjust (i.e., rows. Columns, data type, etc.) data on the BlueSky Statistics data grid, irrespective of how the data was loaded into the data grid with the file open option or by copying and pasting from Excel/CSV file.

      Renaming output tabs

      Double-clicking on the output tab will open a dialog box asking for the new name. The user can type in a name to rename the output tab.

      Enhanced Pie Chart and Bar Chart

      Graphics > Pie Charts > Pie Chart
      Graphics > Bar Chart

                    The pie chart and bar chart have been enhanced to show % and counts on the plot.

      Scatterplot Matrix

      Graphics > Scatterplot Matrix

      The Scatter Plot Matrix dialog has been added.

      Scatterplot with mean and confidence interval bar

      Graphics > Scatterplot > Scatter Plot with Intervals

      A Scatter Plot dialog with mean and confidence interval bar has been made available with an unlimited number of grouping variables for the X-axis to group a numeric variable for the Y-axis.

      Enhanced Scatterplot with both horizontal and vertical reference lines

      Graphics > Scatterplot > Scatter Plot Ref Lines

      The Scatterplot dialog has been enhanced so that users can add an unlimited number of reference lines (horizontal and vertical axis) to the plot. 

      Enhancements to BlueSky Statistics R Editor and Output Syntax/Code Editor

      For R-programmers many enhancements have been made to the BlueSky R Editor and the output syntax/code editor to improve ease of use and productivity with tooltips, find and replace, undo/redo, comment/uncomment blocks, etc.

      Enhanced Normal Distribution Plot

        Distribution > Normal > Normal Distribution Plot with Labels 

        Automatic randomization of generating normal sample distribution

          Distribution > Normal > Sample from Normal Distribution

          In addition to setting a seed value for reproducibility, the default option has been set to randomize automatically the sample data generation every time.

          Automatic randomization of design creations of all DoE designs

            DOE > Create Design > …. 

            In addition to setting a seed value for reproducibility, the default option has been set to randomize the creation of any DoE design every time automatically.

            Enhanced Distribution Fit analysis

              Analysis > Distribution Analysis > Distribution Fit P-value

              The distribution fit analysis has been enhanced to compute AD, KS, and CVM tests and show test statistics, as well as corresponding p-values. These assist users in determining the best fit in addition to the existing AIC and BIC values.

              Moreover, an option has been introduced for users to see only the comparison of distributions and skip displaying the analysis of the individual distribution fit analysis.

              Tolerance Intervals

                Six Sigma > Tolerance Intervals

                A new Tolerance Intervals analysis has been introduced. The tolerance interval describes the range of values for a distribution with confidence limits calculated to a particular percentile of the distribution. These tolerance limits, taken from the estimated interval, are limits within which a stated proportion of the population is expected to occur.

                Equivalence (and Minimal Effect) test

                  Analysis > Means > Equivalence test

                  This new feature tests for mean equivalence and minimal effects.

                  Nonlinear Least Square – all-purpose Non-Linear Regression modeling

                    Model Fitting > Nonlinear Least Square

                    Performs non-linear regression with flexibility and many user options to model, test, and plot.

                    Polynomial Models with different degrees

                      Model Fitting > Polynomial

                      Computes and fits an orthogonal polynomial model with a specified degree. Also, optionally compares multiple Polynomial models of different degrees side by side. 

                      Enhanced Pareto Chart

                        Six Sigma > Pareto Chart > Pareto Chart

                        A new option has been added for data that does not have a count column but only has the raw data. Automatically computes cumulative frequency from Raw Data for plotting.

                        Frequency analysis with an option to draw a Pareto chart

                          Analysis > Summary > Frequency Plot

                          A new dialog has been introduced to plot (optionally) the Pareto Chart from the frequency table and, if desired, display the frequency table on the Datagrid.
