You may know that many statistical software packages can generate biplots.
However, GGEbiplot not only generates perfect biplots of all possible
models but also analyzes them in all possible ways, many of them novel
and unique. Further, GGEbiplot is created for use by all researchers, not just
stats wizards...

ANOVA
|
|
|
This is a
new addition of GGEbiplot. It allows reading any type of data with factors
and traits in parallel columns. No particular order is required for the
columns. For most plant breeders and agricultural scientists, this group
of functions should be sufficient for needs for conventional statistical
analysis. These functions are superior to some of the GLM functions in the
SAS software, in addition to its user-friendliness: all operations are
through button-clicking.
Also note: these ANOVA functions are
available for free for any type or size of data in the
Beta GGEbiplot. |

Main
Effects ANOVA |
|
To conduct analysis of
variance regarding any of the traits, to calculate mean values and LSD
(least-significant difference) scaled mean values for the selected factor,
which allows easy comparison among different levels of any the factor
(year, location, variety, etc.) |
|
|
4-Way ANOVA |
|
To conduct ANOVA for
variety test data from a single environment, from multi-environments in a
single year, and from multi-environments in multiple years for ALL or
SELECTED traits. |
ANOVA can be conducted and LSD-standardized values generated for
year-location-genotype-trait data or any data of similar structures:
