In packDAMipd: Decision Analysis Modelling Package with Parameters Estimation Ability from Individual Patient Level Data

Description

Function to check if the parameters are sufficient to define a distribution and if not see if we can estimate the parameters from the given parameters, e.g. for gamma distribution, shape and rate can be estimated from mean and sd

Usage

check_estimate_required_params(the_expr, distr_key)

Arguments

the_expr	the expression that contain the definition
distr_key	the keyword used to generate random numbers in stats package

Details

if the distribution is gamma and the parameters are mean and sd we can estimate shape and rate from mean and sd. This function is not usually needed by the user

Value

the parameters required

Examples

check_estimate_required_params("gamma(mean = 10 ,sd = 1)", "gamma")
