Create barebones version of the FEM

[ld-archer]

Cut down the current model to only include information on key variables.

To Keep (outputs and predictors):

• Demographics
  • Mortality
  • Age
  • Sex
  • Education
  • Race?
  • Work Status
    • Employed
    • Unemployed
    • Retired
  • Relationship Status
    • Married
    • Single
    • Cohabiting
    • Widowed
• Chronic Diseases
  • Cancer
  • Heart Disease
  • Diabetes
  • Alzheimer's
  • Dementia
  • Lung Disease (for smoking intervention)
  • High Cholesterol (for intervention)
  • High Blood Pressure? Will keep in first iteration
  • Stroke
• Wealth indicators
  • Total Family Wealth
  • Total Couple Income
• Risk Behaviours
  • BMI
  • Smoking
  • Drinking
• Functional Limitations
  • adlstat
  • iadlstat

Some other things are required (ID, weighting vars, some others I can't remember now).

On a new branch we will remove everything else from the model (leaving the .cpp files alone, it doesn't matter if we have defined variables that we are not including).

REMOVED:

• loneliness summary score [1,3]
  • lnlys (refactored to lnly)
• Hip Fracture
  • hipe
• Exercise status
  • vgactx_e
  • mdactx_e
  • ltactx_e
  • exstat
  • exstat indicators
• Parkinsons disease
  • parkine
• Asthma
  • asthmae
• Health Limits Work
  • hlthlm
• Psychiatric Problems
  • psyche
• Arthritis
  • arthre

Checking outputs now to see if the loss of variables have improved/worsened projections or any specific model. Paying particular attention to BMI as this was good before the change. If all is good, will move on to checking against external data using the AgeUK Almanac.

Speaking to Bryan last Monday (4th Jan 21), he reminded me there is an even easier way to run multiple simulations with different variable sets than what I have done already here. Instead of limiting the variables in the starting populations, we can limit what is actually transitioned and output by the model using the settings files instead.

Therefore, the 'barebones' branch with the reduced model has been replaced with a 'core' model on the multisim branch, about to be merged with development.

Some slight changes between the barebones and core model:

• Core model does not include any information on wealth or income (lotatotb and logitot removed)
• Core model does not include marriage status (mstat removed)

Running the core model is very similar to other configurations, with the command make core. Eventually, a new debug script (or adapted old one) will be written for the core models and runnable via make core_debug.
