ms.sev (version 1.0.4)

ms_sev: MS-Severity

Description

Estimates the severity score for the user supplied data frame of patients.

Usage

ms_sev(data, type="global_armss", range = 2, matrix=F, omsss=FALSE)

Arguments

data

A dataframe containing the variable "edss" for every individual and "age" if "armss" is requested. For MSSS estimation, a variable "dd", corresponding to the disease duration, is needed.

type

Specification of the type of severity calculation. Default is global armss. Other options are "local_armss", "local_msss" and "global_msss".

range

The age-range from which to include individuals in the local ARMSS and local MSSS-estimations. The default age-range is 2 years.

matrix

If true, the global MSSS-matrix is returned. Please note that this option only works for global MSSS and global ARMSS.

omsss

If true, the old MSSS-score will be estimated and returned. Please note that this option only works for the global MSSS.

Value

Returns the initially supplied dataframe with a column added with the requested type of severity score. If "matrix" is set to true, the ms\_sev will return a list where the first element is the data frame with the added severity score, and the second item is the requested ARMSS/MSSS matrix. If omsss is set to TRUE, both the old and the updated MSSS matrix will be returned.
