Data analysis is conducted using the R Software Environment in conjunction with the SGP Package. Broadly, the analysis takes place in 6 steps.
Because these steps are almost always conducted simultaneously, the SGP Package has wrapper functions
abcSGP
and
updateSGP
that "wrap" any or all of the above 6 steps into a single function call and simplify the source code associated with the analysis.
For annual state testing systems like Utah, SGP analyses are conducted each year using a similar script. Links to the annual data analysis scripts and accompanying documentation are provided as follows:
