simulation for l3c pasc study

VAX-PASC sim

Longitudinal Simulation of the effect of vaccine timing on Long Covid (PASC).

Assumptions

• time-varying covid and vax are a function of time since last covid or vax
• time-varying pasc is a counting process. new cases are a function of time between last vax and last covid

Data Dictionary

• obs_month is a binary indicator of any visits occuring in a given month

Modifications

11/1/23

• Changed race and data type to factors
• Added vax brand data to both basline (as counts) and time varying (as indicators)
• Made metformin a point indicator variable rather than a counting process variable
• Modified the sim to increase the probabilities of events:

##   month_covid_prob month_vax_prob final_pasc_prob final_death_prob
## 1       0.09257143         0.0385           0.285            0.084

• Changed imputation strategy to 0’s for everything but the counting processes (death and covid)
