* Update multiple places where `df.empty` is used and replaced with `df.dropna().empty`. * Update documentation for running CalTRACK hourly methods.
2.1.5
-----
* Fix zero division error in metrics calculation for several metrics that would otherwise cause division by zero errors in fsu_error_band calculation.
2.1.4
-----
* Fix zero division error in metrics calculation for series of length 1.
2.1.3
-----
* Fix bug related to caltrack billing design matrix creation during empty temperature traces.
2.1.2
-----
* Add automatic t-stat computation for metered savings error bands, the implementation of which requires expicitly adding scipy to setup.py requirements. * Don't compute error bands if reporting period data is empty for metered savings.
2.1.1
-----
* Fix degree day ranges (30-90) for prefab caltrack design matrix creation methods. * Fix the warning for total degree days to use total degree days instead of average degree days.
