The weight is used as the \(w_i\) parameter in pk.calc.sparse_auc()
sparse_auc_weight_linear(sparse_pk)A numeric vector of weights for sparse AUC calculations the same
length as sparse_pk
A sparse_pk object from as_sparse_pk()
$$w_i = \frac{\delta_{time,i-1,i} + \delta_{time,i,i+1}}{2}$$ $$\delta_{time,i,i+1} = t_{i+1} - t_i$$
Where:
is the weight at time i
are the changes between time i-1 and i or i and i+1 (zero outside of the time range)
is the time at time i
