epicR v0.10.0

New Features

• Smoking module has now been completely revamped to match smoking and pack-years trends from POHEM
• Background mortality now adjusted for current and former smokers
• validate_smoking () now produces new graphs to monitor pack-years over years
• Re-calibrated population and background mortality
• Exacerbation rates per GOLD stages now according to Hoogendoorn paper
• Iterative_incidence () optimize to use less memory

Bug Fixes and Minor Improvements

• Fixed a bug which resulted Cget_output and C_get_output_ex returned zero number of 40 years old for multiple outputs.

epicR v0.9.0

New Features

• Re-calibrated population and background mortality
• Updated LHS equations based on modifications to Zafar's work
• Some graphs now exported automatically through export_figures ()
• Recalibrated COPD incidence

Bug Fixes and Minor Improvements

• Fixed a bug which resulted Cget_output and C_get_output_ex returned zero number of 40 years old

epicR v0.8.1

New Features

• sanity_check() now performed automatically.
• Continuous integration implemented with Travis CI.

Bug Fixes and Minor Improvements

• Certain internal functions are now longer exported to user environment.
• Documentation created for all exported objects.
• model_input no longer a global variable.

epicR v0.8.0

New Features

• Added utilities, costs, and disutility values.

epicR v0.7.0

New Features

• COPD incidence rate has been re-calibrated using iterative approach.

epicR v0.6.0

New Features

• FEV1 decline equations with conditional bivariate distribution now implemented.
• Exacerbation mortality now a logit function of age.
• Exacerbation mortality calibrated to result in an overall severe and very severe exacerbation rates of ~11%
• Re-calibrated background mortality.

Bug Fixes and Minor Improvements

• sanity_check() updated to work with log scale
• validate_mortality now shows better-looking graphs

epicR v0.5.1

New Features

• An input_ref* variable now holds all the reference list for input values.
• Background mortality readjusted with a simulation population size of 100 million.

Bug Fixes and Minor Improvements

• R codes reformatted and cleaned according to Hadley Wickham's style guide.
• Fixed a bug with the 4th test of sanity_check()
• validate_mortality now leaner and improved
• fixed a bug with version number

epicR v0.5.0

New Features

• FEV1 tail now adjusted for each individual.
• Background mortality adjusted: COPD-related deaths are now subtracted from background mortality to avoid double counting of COPD-related death.

Bug Fixes and Minor Improvements

• Minor code cleaning and housekeeping

epicR v0.4.0

New Features

• Exacerbation regressions has been recalculated and calibrated based on MACRO study to produce results similar to Najafzadeh et al (2012).

• Exacerbations are now classified using 4 stages as opposed to 3: mild, moderate, severe, and very severe. The latter two can be fatal.

Bug Fixes and Minor Improvements

• Exacerbation rates now calculated per GOLD stage as well.
• Improvements to report_exacerbation_by_time()
• Base number of agents now increased to 500,000, from 10,000.

epicR v0.3.1

New Features

• epicR now compatible with R 3.4 under Mac OS.

Bug Fixes and Minor Improvements

• Fixed an issue with clang that would prevent installation from GitHub when using R 3.4 with Xcode 8.3.x.
