Developed at UC Berkeley, SDA allows users to do statistical analysis online without the need for any client-side software (such as SPSS, SAS, or Stata).
With SDA you can:
- Browse the codebook describing a dataset
- Calculate frequencies or crosstabulation (with charts)
- Do comparison of means
- Calculate a correlation matrix
- Compare correlations
- Perform multiple regression
- Perform logit/probit regression
- List values of individual cases
- Recode variables (into public work area)
- Compute a new variable
- List/delete derived variables
- Download a customized subset
A major limitation of SDA is that you can only analyze datasets that reside on an SDA server, and cannot import other data.
