New features in XLSTAT 2018
New features added to XLSTAT in 2018 include:
- Random Forests: This powerful machine learning algorithm allows to make predictions based on multiple decision trees. It works for both classification and regression tasks. Available in all XLSTAT solutions under the Machine Learning menu.
- Proportional Hazards Model with interval censored data: A regression approach for modeling survival times using interval-censored data. Both quantitative and qualitative explanatory variables can be taken into account. This new feature is available in XLSTAT-Biomed, XLSTAT-Ecology and XLSTAT-Premium
- Correlation tests: New options for sorting and filtering variables, and a more ergonomic way to display correlation matrices as an image. The above options can be accessed in all XLSTAT solutions within the Correlation tests dialog box.
- XLSTAT Designer: With this new tool, design your own customized statistical applications in Excel based on XLSTAT features. Available in all XLSTAT solutions, the XLSTAT Designer can be found in the main XLSTAT menu.
- Word cloud: A powerful text visualization tool for quickly identifying important words in a document. Colors can be defined by the user for a more customized output. Available in all XLSTAT solutions under the Visualizing data menu.
- ELECTRE I: Commonly used in decision making, this method aims to detect, compare and rank solutions to a multi-criteria problem. Available in all XLSTAT solutions under the Decision aid menu.
- Conjoint design: It is now possible to take into account prohibited pairs when creating a full-profile or a choice-based conjoint design. Available in XLSTAT-Marketing & XLSTAT-Premium under the Conjoint analysis menu.
- Random Forests: Several new options including Random Input method and Mean Decrease Accuracy for measuring variable importance. Available in all XLSTAT solutions under the Machine Learning menu.
- Feature extraction: Transform a collection of text documents into feature vectors based on the Bag-Of-Words model. The output can be used to compare corpus in the Word Cloud tool or to run a classification. Available in XLSTAT-Marketing under the Text mining menu.
- Probability Plot: This new graphical feature allows you to visually control if a sample comes from a population that follows a given distribution. Available in all XLSTAT solutions under the Visualizing data menu.
- Correlation tests: It is now possible to compute the lower and upper bound confidence intervals for Pearson, Spearman and Kendall correlation coefficients. Available in all XLSTAT solutions under the Correlations/Associations tests menu.
- ANOVA: Lower and upper confidence intervals can now be reported for multiple comparisons tests when running a one-way or multi-way ANOVA. Available in all XLSTAT solutions under the Modeling data menu.
- Factorial analysis of mixed data: Explore a group of observations described by both quantitative and qualitative variables using the PCAmix method
- ELECTRE 3: Classify a set of solutions to a decision-making problem from best to worst
- Importing data into Excel: Import various file formats into Excel in few clicks (SPSS, Minitab, SAS, Stata...)
- Multiple Correspondence Analysis: Perform a MCA on Burt table Link categories of a variable on a factorial map
- Comparison plots: Visualize and interpret the results of a two-sample student test in a single chart
- Search box: Find your functionalities within the XLSTAT menu in 1-click
- Fuzzy K-means: An unsupervised clustering algorithm for organising large data sets into groups. It can be used for document classification and many other applications. Available in all XLSTAT solutions under the Machine Learning menu.
- Conjoint Survey Design: It is now possible to generate different question sets for different respondent groups in conjoint surveys. Available in XLSTAT-Marketing under the Conjoint Analysis menu.
- Johnson Transformation: Transform your data into a normal distribution using the Johnson transformation method. It can be used for data including zero and negative values. Available in all XLSTAT solutions under the Preparing Data menu.
- Temporal Dominance of Sensations: New options are available for defining either automatically or manually the smoothness of a TDS curve. Available in the XLSTAT-Sensory under the Text Mining menu.
