I am in an advanced analytics group in a market research company.
Other than routine procs in Base SAS (like import, export, freq,corr, univariate) and SAS/STAT (means, reg, factor, anova, glm, cluster, phreg, logistic), I make heavy use of macros and SAS/IML. Also make fair amount of use of optmodel from SAS/OR and have started using proc mcmc.
Modules:
1. Base (of course!) incuding macros
2. Stat,
3. ETS (rarely)
4. Access for PC Files
Procodures:
Many of them, top 10 being:
1. Logistic
2. GLM
3. Fastclus and Cluster
4. Reg
5. Means
6. Freq
7. Univariate
8. Genmod
9. Calis
10. ARIMA
Industry:
Multiple: as and analytics and quantitative research professional, I get to address business questions from different domains like financia services (Insurance, banks - credit cards and retail loans), retail, beverage, aviation, education, and so forth.
I should use mostly DI Studio; but whenever I can I switch to Base. I also use a lot of WA and EM; sometimes STAT/GRAPH and IML.
I mostly stick to proc sql, proc transpose, import/export, datasets and contents. Most of the stuff I do need data step's functions and macro's code.
We work for the public administration.
