Sas profile csg_0413

  1. 1. C.S. Ganti SAS Modeling Profile April 3, 2013Estimate how many statistical models you have built using SAS or otherstatistical software?at least 80What types of statistical models do you have experience with?Log-Linear Regression Logistic Regression Simple, Multiple and Multi-variate MultipleRegression; Univariate Distribution Fitting – Log Normal, Poisson, Gamma, Inverse Gamma;Monte-Carlo Simulations of Systems (financial, engineering and others);Describe your statistical analysis experience?Extensive for over several decades, right after graduate school, in various applicationareas / services; remote sensed ecological information analyses; transportation hazard andoil spill risk assessment; loss prevention engineering / safety control and research;insurance risk quality and loss assessment; loss profiling and Insurance risk / score (alacredit score) development for account and market segmentation; auto accident safety / theftdeterrent systems effectiveness analyses;Briefly describe your logic towards the statistical model or statistical analysisthat youve chosen and business problem involved?Study and understand the problem relating to business issues; interact with business usersand audience; study data availability / feasibility; collect primary data; cleanse, data QC;data input, data processing; implement procedures under available systems (OS/Languages / stat software); model problems; verify hypotheses; accuracy of results andexplicability ; validate with subsets of data (hold out concepts); summarize results andconclusions; track the model stability over time; refine as necessary with new information;Do you have experience pulling your own data?Yes extensivesasprofilecsg0413-130410122317-phpapp01.doc Page 1 of 4
  2. 2. C.S. Ganti SAS Modeling Profile April 3, 2013From what resources have you pulled the data?Hard copy reports, external data bases US Govt. agencies: DOL FRB DOT DOC USCGUSGS; internal (own company cross departmental / cross organizational) and tradeassociations etc API; professional society (ASME) etc.List the query language you have used to pull your data?SAS / SQL; MS ACCESS SQL; COGNOS / SQL (IMPROMPTU); FOCUSWhat types of analysis are you experienced with running?Base Descriptive and Inferential statistics all statistical procedures and functions andcustom programmingHow do you go about determining which data is important to include in yourmodeling & analysis?By studying various relations of the process; predicting variables vs. the predicted variablecorrelations and significance; and after model estimation, checking for the significance ofeach variable included (by their p values in case of regression) whether it is sufficient,complete and explains with as few logical and explicable variables (parsimony is the key)What databases have you used?FOCUS IBM MAIN-FRAME PC ACCESS DBASE IMS RBASE ORACLE EXTRACTS IN TO COGNOS RELATIONAL TABLESList the statistical analysis software, and what versions you have experiencedwith? (SAS, SPSS, SAP, Minitab, etc)SAS V8.0 SAS 9.1 PC SYTAT SPSSsasprofilecsg0413-130410122317-phpapp01.doc Page 2 of 4
  3. 3. C.S. Ganti SAS Modeling Profile April 3, 2013What operating systems (platforms ) have you run the statistical analysissoftware on?PC WINPRO, IBM OS, VMS,What volume of datasets do you have experience with?Excess of Several MillionWhat type of variable have you looked at & worked with?All Types, Numeric, Date, Alpha Numeric, Logical (Boolean), Text etcHow many variables?Up to several hundredsWhat procedures have you used? (Procs )All Procedures found in typical stat software; Tables (Frequency Etc) descriptive statisticsCorrelations and regression; General Linear Models Logistic Log-linear Discriminiantanalysis Cluster analysis Principal Component Non parametric stats etcCan you describe to me the purpose behind using each SAS procedures? DATA step: procedure reads raw data from various sources (data tables / engines) ordirect input data from and process and create SAS data sets or further process SAS datasets for later use in the proc steps; can merge, concatenate data sets;PROC step procedures further process, consolidate, generate reports, charts or statisticalanalysesExamples are:PROC format assigns formats to variables; PROC SORT sorts data organize output orsummarize data outputs SAS data sets; PROC CONTENTS displays contents of dataincluding variable information etc. PROC print prints data; PROC REPORTProc Means Tabulate Freq etc provide descriptive statistics, inference, model and analysesProc GCHART and GPLOT are used to generate charts and plots.sasprofilecsg0413-130410122317-phpapp01.doc Page 3 of 4
  4. 4. C.S. Ganti SAS Modeling Profile April 3, 2013Describe your familiarity with macros?Very goodWhat statistical methodologies are you experienced with?Univariate and Multi-variate Regression; Logistic and Log-Linear Regression, Distributionfitting; Hypothesis testing; Monte-Carlo Simulation;sasprofilecsg0413-130410122317-phpapp01.doc Page 4 of 4
