Hosted Network Licensing Available
Has your team wanted to take advantage of our floating license options, but you weren't sure about getting a license server? We now have an option for experimenters to use a floating license that's hosted on a Stat-Ease server in the cloud! Your team can use the same license globally, without the hassle of your IT group needing to manage it themselves. With the license being the only thing in the cloud, there are no data security issues to consider, either. Contact us today for pricing and with your questions!
Dive into Diagnostics for DOE Model Discrepancies
The purpose of running a statistically designed experiment (DOE) is to take a strategically selected small sample of data from a larger system, and then extract a prediction equation that appropriately models the overall system. The statistical tool used to relate the independent factors to the dependent responses is analysis of variance (ANOVA). This article will lay out the key assumptions for ANOVA and how to verify them using graphical diagnostic plots.
