Good company
Dembe, Partridge, and Geist (2011, pdf), in a paper recently published in
Good company. Both are, in our humble opinion, excellent packages, although we admit to have a preference for one of them.
We should mention that the authors report that SAS usage grew considerably during the study period, and that Stata usage held roughly constant, a conclusion that matches the results in their Table 1, an extract of which is
| 2007 | 2008 | 2009 | 2007-2009 | |
|---|---|---|---|---|
| total articles | 393 | 374 | 372 | 1,139 |
| included articles | 282 | 308 | 287 | 877 |
| % Stata used | 48.3 | 42.6 | 47.4 | 46.0 |
| % SAS used | 37.2 | 43.1 | 47.4 | 42.6 |
The authors speculated that the growth of SAS “may have been stimulated by enhancements […] that gave users the ability to use balanced repeated replication (BRR) and jackknife methods for variance estimation with complex survey data […]”. Since those features were already in Stata, that sounds reasonable to us.
Let us just say, good company. Good companies.
