Description: Calculate comorbidities, and perform fast and accurate
validation, conversion, manipulation, filtering and comparison of ICD-9-CM
(clinical modification) codes. ICD-9 codes appear numeric but leading and
trailing zeroes, and both decimal and non-decimal "short" format codes
exist. The package enables a work flow from raw lists of ICD-9 codes from
hospital billing databases to comorbidities. ICD-9 to comorbidity mappings

Title: EM by the Method of Weights for Incomplete Categorical Data in
Author: Lorenz Brachtendorf <Lorenz.Brachtendorf@gmx.de>, Stephan Dlugosz
Description: Provides an estimator for generalized linear models with incomplete
data for discrete covariates. The estimation is based on the EM algorithm by the
method of weights by Ibrahim (1990) <DOI:10.2307/2290013>.

Title: 'ICD' Programs for Injury Categorization in R
person("Adam", "Black", email = "ablack3@gmail.com", role = c("aut", "cre", "cph")),
person("David", "Clark", role = c("aut", "cph")))
Description: Categorization and scoring of injury severity typically involves
trained personnel with access to injured persons or their medical records. 'icdpicr' contains a function
that provides automated calculation of Abbreviated Injury Scale ('AIS') and Injury Severity Score ('ISS')
from International Classification of Diseases ('ICD') codes and may be a useful substitute to manual injury
severity scoring. 'ICDPIC' was originally developed in 'Stata', and 'icdpicr' is an open-access update
that accepts both 'ICD-9' and 'ICD-10' codes.
