id_attributes | R Documentation |
Stores metadata related to the ID variables used to index input_mats and transformed parameter objects already predicted from covariates.
id_attributes( strategy_id, n_strategies, patient_id, n_patients, state_id = NULL, n_states = NULL, transition_id = NULL, n_transitions = NULL, time_id = NULL, time_intervals = NULL, n_times = NULL, sample = NULL, n_samples = NULL, grp_id = NULL, patient_wt = NULL )
strategy_id |
A numeric vector of integers denoting the treatment strategy. |
n_strategies |
A scalar denoting the number of unique treatment strategies. |
patient_id |
A numeric vector of integers denoting the patient. |
n_patients |
A scalar denoting the number of unique patients. |
state_id |
A numeric vector of integers denoting the health state. |
n_states |
A scalar denoting the number of unique health states. |
transition_id |
A numeric vector denoting the health state transition. This is only used for state transition models. |
n_transitions |
A scalar denoting the number of unique transitions. |
time_id |
A numeric vector of integers denoting a unique time interval. |
time_intervals |
A |
n_times |
A scalar denoting the number of time intervals. Equal to the
number of rows in |
sample |
A numeric vector of integer denoting the sample from the posterior distribution of the parameters. |
n_samples |
A scalar denoting the number of samples. |
grp_id |
An optional numeric vector of integers denoting the subgroup. |
patient_wt |
An optional numeric vector denoting the weight to apply to each patient within a subgroup. |
When using the ID variables to index input_mats, the sorting order
should be the same as specified in expand.hesim_data()
; that is,
observations must be sorted by prioritizing: (i) strategy_id
, (ii) patient_id
,
(iii) the health-related ID variable (either state_id
or transition_id
),
and (iv) time_id
. When using ID variables are used to index transformed parameter
objects and sample
is used for indexing, then observations must be sorted by
prioritizing: (i) sample
, (ii) strategy_id
, (iii) patient_id
,
(iv) the health-related ID variable, and (v) time_id
.
