I am looking for a .NET library for time series work. It can be either free or commercial. My basic requirements are the following:
- Handle time series in varying frequencies (daily, business daily, week ending Friday, monthly, quarterly, annual, etc).
- Convert between different calendar frequencies, going from both high to low frequency and low to high frequency.
- Supporting time series transformations like moving averages, annualized percent changes, etc.
- Allowing time series to be combined together; for instance time series A = B+sqrt(C)
