Description Usage Arguments Details References
This function computes S0 and S1 in counting process.
1 | Compute_S01(est, x, y, kk, event, group, save, group.in.train)
|
est |
The model fitting details from the k^th cause-specific hazards model. |
x |
The design matrix associated with the k^th type of failure, of dimension n observations * p_k covariates. |
y |
The survival response associated with the k^th type of failure. |
kk |
The k^th type of failure. |
event |
This is an internal binary indicator to specify if any type of failure occurs at a given time. |
group |
The name of the group covariates (if any). If specified, the cumulative hazards will be estimated for each group seperately. Default is |
save |
An option to save the computed S0 and S1. It is highly recommended for large-scale dataset to improve the computational efficiency. Default is |
group.in.train |
This argument is valid only when the group argument is specified. If group is presented in both data and newdata, use |
This function computes
S^{(0,1)}(\hat{β}, t; z_{0}) = \frac{1}{n}∑_{i^{\prime}=1}^{n}I(\tilde{T}_{i^{\prime}} ≥ t) \exp(\hat{β}^{T}Z_{j})Z_{j}^{\otimes 0,1}
