Interprets a Poisson joint formula and makes necessary changes to data

get_form_joint uses two event formula, a shared formula, and data.table, to fully describe the model for a joint Poisson model.

Usage

get_form_joint(formula_list, df, nthreads = as.numeric(detectCores())/2)

Arguments

formula_list

a list of formula objects, each written in Colossus notation. See the vignette("Equation_Expression") vignette for details. Each formula should include the elements specific to the specified event column. The list can include an entry named "shared" to denote shared terms. The person-year and strata columns should be the same.

df

a data.table containing the columns of interest

nthreads

number of threads to use, do not use more threads than available on your machine

Value

returns a class fully describing the model and the updated data
