In sheejamk/MarkovModel: Decision Analysis Markov Model

Description

Function to check if the parameters are sufficient to define a probabiltiy 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_estimating_required_params(params_found, required_params, the_expr,
  distr_key)

Arguments

params_found	given parameters for generating ransom numbers
required_params	the required parameter by the R code (stats package)
the_expr	the expression that contain the definition
distr_key	the keyword used for generating random numbers in R stats package e.g. rgamma for gamma distribution

Value

the keyword that shoudl be used in R for generating random numbers

Examples

check_estimating_required_params(c("mean,sd"),c("shape", "rate"), "gamma(mean =10 ,sd=1)", "gamma")
