* NOTICE OCMAP and MPDS USERS *
MPDS detailed mortality and population data are now available for 2004. The latest update includes the tenth revision of the ICDA. Please contact our office for more details or for information on how to order new or updated rates. MPDS rates are also now accessible via the Internet from our server.

OCMAP-PLUS Fact Sheet
Currently available cohort analysis programs do not enable a comprehensive, flexible and efficient analysis of mortality rates and standardized measures in relation to multiple and diverse work history and exposure metrics. The OCMAP software for historical cohort analysis has been entirely redesigned and extended to permit these capabilities .
Limitations eliminated from OCMAP (Version 2) include:
- Inability to process more than two work history exposure agents per run
- Large memory requirements for person-day arrays
- Restrictive upper bounds on some processing parameters
- Need to reprocess person-days in multiple runs
- No death rate link to geographic area
- Highly centralized task-based processing
- Limited control over report generation
- Absence of data exporting to other statistical packages
New analytic and operational features include:
- Simultaneous accumulation of person-day counts by the demographic factors: age, calendar time, race, sex and geographic area; up to 24 general stratifying factors (e.g., plant, year of birth, year of hire); the work history factors: department (work area), job title, duration of employment and the time since first (or last) employment; and for up to 8 agents, the work history-based exposure indicators: duration of exposure, time-weighted cumulative exposure, average intensity of exposure (cumulative, moving or static) and lagged exposure
- Use of unlimited cohort sizes, up to 124 standard rate files, 124 causes of death and 1000 jobs per work history
- Creation of internal rates to serves as standard populations in other OCMAP-PLUS runs
- Creation of multi-factor "risk sets" for use in Cox proportional hazards modeling of cohort rates
- Exporting of data files for input to standard statistical packages (e.g., Stata, SAS, EGRET,S-PLUS, Epicure)
- Increased operational efficiency through:
- Elimination of memory requirements for person-day arrays (multi-dimensional person-day arrays are written to disk files, the only limitation is the amount of free disk space)
- Creation of task-based processing modules (death rate interfaces, person-day counts, report generation and data base exports are serially performed via separate modules)
- Minimization of redundant person-day processing in multiple runs
- Expanded error messages
- Mainframe and UNIX ® versions available, long-range plans include OCMAP-PLUS for Windows ® is currently in beta testing.
