ll_AdPaik_centre_eval {TimeDepFrail} | R Documentation |
Evaluation of Model Group log-Likelihood
Description
Evaluation of model group log-likelihood at the provided parameter vector and data. This function is internally called by 'll_AdPaik_eval' to evaluate the log-likelihood function, considering all and only the individuals belonging to a group.
Usage
ll_AdPaik_centre_eval(params, dataset, dropout_matrix, e_matrix)
Arguments
params |
Parameter vector. |
dataset |
Matrix of dataset regressors, with a number of rows equal to the number of individuals in a cluster. |
dropout_matrix |
Binary matrix indicating in which interval of the time domain and individual failed. For an individual, the sum of the row elements must be equal to 1 (if he/she failed) or 0 (if he/she does not failed). It has dimension equal to (n_individuals, n_intervals) |
e_matrix |
Matrix of dimension (n_individual, n_intervals), where each element contains the evaluation of the temporal integral, performed through the function @time_int_eval. |
Value
Group log-likelihood evaluation
