Needful Stats
Needful Stats is a collection of programs and Matlab routines that we developed for our consulting work. They are currently available as Matlab callable functions. Stand-alone versions for Windows will become available later.
The following programs are available:
Autolyze
Point-and-Click data analysis is nice and very insightful. However, once you have reached a certain level of experience, Point-and-Click can be painstakingly slow. For these more experienced users we offer Autolyze; a single-click program for the analysis of multivariable regression problems, aimed at designed experiments.
Autolyze performs:
- Stepped Multiple Linear Regression (MLR)
- First-order models
- Two-factor interaction models
- Quadratic model
- All-in-1 Word document report
Props
Props is a tool for principal-properties design tightly knitted with Design Expert software.
Principal properties design is a way of dealing with categorical variables with many levels, based on Principal Component Analysis (PCA).
Gonogo
Gonogo serves as a feasibility study for multivariate regression analysis by performing:
- Near-replicate analysis
- Maximum R2 estimation
