Description

Report/error_measures.R redefines (looks like copy-pasted, but verify) error measures from evalcast. We want them to match exactly and also use new efficient versions. Error functions are used in Report/create_reports.R.

https://github.com/cmu-delphi/forecast-eval/pull/245 copy-pastes the efficient versions from https://github.com/cmu-delphi/covidcast/pull/602. Once https://github.com/cmu-delphi/covidcast/pull/602 is merged, pull from evalcast instead.

Contributor guide

Research direction
Inspect error measure functions in forecast eval's Report/error measures.R and compare with evalcast's implementation. After evalcast PR is merged, replace copy pasted code with calls to evalcast's functions, ensuring exact match.
