stats.ini, the default statistics file
The stats.ini file controls some of the statistics settings and determines which tests are available to users in the Statistics dialog box in Windows-based Quanvert.
A default stats.ini file is added to the Quanvert directory during installation, but you can set up a specific stats.ini file for each project, place it in the project directory and pack it along with the database.
When a user opens the Quanvert Statistics dialog box, Quanvert looks for a stats.ini file to provide the default settings. Quanvert looks first in the project directory for a stats.ini file and, if it exists, uses the tests and options it defines. If a stats.ini file does not exist in the project folder, Quanvert looks for the default stats.ini file in the Quanvert installation directory.
The settings in the stats.ini file override the t-statistics section in the quantime.ini file.
Note If the user saves their Quanvert options (by using the Save options command on the Format menu), Quanvert creates a new stats.ini file in the project directory defining the statistical tests and options that are currently set. If a stats.ini file already exists in the project folder, Quanvert silently overwrites it.
The default stats.ini which is created in the Quanvert directory during installation is as follows:
[statistics available]
tstat1=colprop
tstat2=colmean
tstat3=netdiff
tstat4=pairedpref
TopLevelOnly=true
[statistics options]
default=built-in
This makes the column proportions, column means, net difference, and paired preference tests available for selection. However, Quanvert automatically selects only the tests and specify the options which apply to the current table as defined in the Quantum run.
The TopLevelOnly=true line means users can only run the tests on tables at the highest level in hierarchical databases.
To change the statistics available by default to all projects, the stats.ini file in the Quanvert directory can be amended and tailored to your user base.
Note Windows-based Quanvert performs special T statistics on columns formed from elements that were defined in Quantum with the ntot option only if the id= option was also specified on the element.
