PoissonCurveSolver: Calculates the likelihood curve for a poisson model directly

In Colossus: "Risk Model Regression and Analysis with Complex Non-Linear Models"

Calculates the likelihood curve for a poisson model directly

Description

PoissonCurveSolver solves the confidence interval for a poisson model, starting at the optimum point and iteratively optimizing each point to using the bisection method

Usage

PoissonCurveSolver(
  df,
  pyr0 = "pyr",
  event0 = "event",
  names = c("CONST"),
  term_n = c(0),
  tform = "loglin",
  keep_constant = c(0),
  a_n = c(0),
  modelform = "M",
  control = list(),
  strat_col = "null",
  model_control = list(),
  cons_mat = as.matrix(c(0)),
  cons_vec = c(0)
)

Arguments

df	a data.table containing the columns of interest
pyr0	column used for person-years per row
event0	column used for event status
names	columns for elements of the model, used to identify data columns
term_n	term numbers for each element of the model
tform	list of string function identifiers, used for linear/step
keep_constant	binary values to denote which parameters to change
a_n	list of initial parameter values, used to determine the number of parameters. May be either a list of vectors or a single vector.
modelform	string specifying the model type: M, ME, A, PA, PAE, GMIX, GMIX-R, GMIX-E
control	list of parameters controlling the convergence, see Def_Control() for options or vignette("Control_Options")
strat_col	column to stratify by if needed
model_control	controls which alternative model options are used, see Def_model_control() for options and vignette("Control_Options") for further details
cons_mat	Matrix containing coefficients for a system of linear constraints, formatted as matrix
cons_vec	Vector containing constants for a system of linear constraints, formatted as vector

Value

returns a list of the final results
