Time series of a heating systems supply temperature. Measured from 18.11.2013 - 05:12:00 to 13.01.2015 - 15:08:00 in 1 minute steps.
This time series provides the truth for the missing values of the tsHeating time series. Thus it is identical
to the heating time series except that no value is missing.
tsHeatingCompleteTime Series (ts) with 606837 rows.
The time series originates from the GECCO Industrial Challenge 2015. This Challenge was about "Recovering missing information in heating system operating data". Goal was to impute missing values in heating system sensor data as accurate as possible. (tools:::Rd_expr_doi("10.5281/zenodo.3884899"))
In order to use this series for comparing imputation algorithm results, there are two time series provided. One series without missing values, which can be used as ground truth. Another series with NAs, on which the imputation algorithms can be applied. The NAs thereby were inserted according to patterns found in similar time series.
There are the two time series:
tsHeating - The time series with NAs.
tsHeatingComplete - Time series without NAs.
