Calculate log of expected values by report date
Computes the logarithm of expected values aggregated by report date. This function takes a vector of logarithmic expected values and an array indicating observations by report date, and then calculates the log of the sum of exponentials of expected values for each report date.
log_exp  Vector of log expected values. 
obs_by_report  Array indicating which observations correspond to each report date. 
\[ \text{log\_exp\_rep}_i = \log\left(\sum_{j \in \text{obs\_by\_report}[i]} \exp(\text{log\_exp}_j)\right) \]
This represents the logsumexp operation over the expected values corresponding to the observations reported on date i.Definition at line 23 of file log_expected_by_report.stan.
