Testing Mediating and Moderating Effects Using the Process Macro
50 minutes
Because most social & business research implies the test of some mediating and/or moderating effects (even, some moderatedmediating…), this seminar is designed to present how the Process macro can easily and usefully help researchers test such effects. The emphasis will be first made on the theoretical rationale for such effects but also, importantly, on how to conduct the analyses and report the results.

Gain Confidence when presenting your Quantitative Results
45 minutes
In these times, when results are expected to be delivered "for yesterday", it is necessary to take some time and review our database to better understand our research. We currently have tools that allow us to validate our information quickly and efficiently. In this webinar, we will review descriptive sensory research.

Deploying an R procedure in Excel using XLSTATR
1 hour
XLSTATR is a revolutionary interface designed to use and write R procedures within XLSTAT dialog boxes in Microsoft Excel®. It has two principal audiences:

Coders able to write XML and R code to generate XLSTAT dialog boxes calling the R engine from Excel;

Statisticians who take advantage of the XLSTATR dialog boxes to call R procedures from Excel without needing to code.
