Calculate expected observations for a given index

Computes the expected observations for a specific time index by combining final observed/imputed expected observation with time effects. This function integrates various hazard effects and reference adjustments to produce the expected observations.

Parameters

i	Index for accessing elements in various arrays.
imp_obs	Array of imputed observed data, organized by group and time.
rdlurd	Array indicating reporting dates lookup reference data.
srdlh	Vector of standardized reporting date log hazards.
refp_lh	Matrix of reference date logit hazards.
dpmfs	Array of indices for accessing reference date effects in refp_lh.
ref_p,rep_h,ref_as_p	Flags indicating presence of reference date, reporting hazards, and reference-as-probability.
g,t,l,p	Group, time, length, and position parameters for data access and processing.
refnp_lh	Vector of non-parametric reference log hazards.
ref_np	Flag indicating presence of non-parametric reference effects.

Returns

A vector of expected observations for the given index.

Note

This function performs several steps:

1. Retrieves the final observed/imputed expected observation for the given group and time.
2. Aggregates various hazard effects using combine_logit_hazards.
3. Combines the final expected observation with the time-varying effects to compute the expected observations using expected_obs.

Dependencies:

• combine_logit_hazards
• expected_obs

Calculate expected observations for a set of indexes

Computes expected observations for a range of time indexes, effectively aggregating individual calculations over a specified range. This function considers various factors like hazard effects, reference adjustments, and grouping to produce expected observations for each index within the range.

Parameters

start,end	Start and end indexes for the allocation range.
imp_obs	Array of imputed observed data, organized by group and time.
rdlurd	Array indicating reporting dates lookup reference data.
srdlh	Vector of standardized reporting date log hazards.
refp_lh	Matrix of reference date logit hazards.
dpmfs,sl,csl,sg,st	Arrays for accessing various indices and supporting data.
ref_p,rep_h,ref_as_p	Flags for presence of different hazard effects.
n	Number of discrete points for observations.
refnp_lh	Vector of non-parametric reference log hazards.
ref_np	Flag for non-parametric reference effects.
sdmax,csdmax	Arrays of maximum start dates and cumulative start dates.

Returns

A vector of expected observations across the specified range of indexes.

Note

This function executes the following steps:

1. Iteratively processes each index in the specified range.
2. For each index, it identifies the relevant group, time, and length parameters necessary for the calculation.
3. Calls expected_obs_from_index for each index to compute the expected observations.
4. Aggregates these individual expected observations into a single vector corresponding to the entire range.

Dependencies:

• expected_obs_from_index
