TAMU ANOVA

ANOVA Extensions to the GNU Scientific Library.

TAMU ANOVA was written at Texas A&M University Department of Statistics by three graduate students, Andrew Redd, Krista Rister, and Elizabeth Young. It was written as a class project for a statistical computing class. For comments or bugs please email Andrew.

ANOVA, or Analysis of Variance, is a method for comparing levels of some continuous response variable between different groups. The main idea is to compare variation within each group to variation between the groups; if the groups vary considerably from one group to another in comparison to the within group variation, we can reject the null hypothesis that all the groups have similar levels of the response variable.

TAMU ANOVA contains both single and two factor ANOVA. Use of the package can be facilitated through linking to the compiled library tamuanova. The package function definitions are accessible through tamu_anova.h. The program must still be linked to the GSL (see GSL documentation on linking and compiling.)

The package can be downloaded here.

The documentation in PDF format can be found here.

UPDATE: TAMU ANOVA 0.2.1 released

UPDATE: TAMU ANOVA 0.2 released

• Improved error handling
TAMU ANOVA now uses the GSL error handler for errors.
• File structure change
the file structure was changed to disallow direct inclusion of the functions. They must now be accessed only through the library.
• Interface changes
Function names have been changed. All function beginning with gsl_tamu_anova have been changed to read tamu_anova so as to not be confused with core GSL functions.
• Computation changes
Slight computation changes were made to avoid cancellation error.
