Development

Placeholder

2.2.4

Add json() serialization for SegmentModel and SegmentedModel.

2.2.3

Change max_value to float so that it can be json serialized even if the input is int64s.

2.2.2

Add warning to caltrack_sufficiency_criteria regarding extreme values.

2.2.1

Fix bug in fractional savings uncertainty calculations using billing data.

2.2.0

Add fractional savings uncertainty to modeled savings derivatives.

2.1.8

Update so that models built with empty temperature data won't result in error.

2.1.7

Update so that models built from a single record won't result in error.

2.1.6

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.

2.1.0

Update the use_billing_presets option in fit_caltrack_usage_per_day_model to use a minimum data sufficiency requirement for qualifying CandidateModels (similar to daily methods).
Add an error when attempting to use billing presets without passing a weights column to facilitate weighted least squares.

2.0.5

Give better error for duplicated meter index in compute temperature features.

2.0.4

Change metrics input length error to warning.

2.0.3

Apply black code style for easy opinionated PEP 008 formatting
Apply JSON-safe float conversion to all metrics.

2.0.2

Cont. fixing JSON representation of NaN values

2.0.1

Fixed JSON representation of model classes

2.0.0

Initial release of 2.x.x series
