unitdid 0.0.6

New Features:

• Export varraw, varerr, covraw, and coverr for explicit variance and covariance adjustment
• Simplify the argument in unitdid for new column names (newnames)

Bug Fixes:

• varerr and coverr is not correctly estimated when k_min is not 0
• Formula for varerr and coverr was incorrect (v0.0.6.1)

unitdid 0.0.5

New Features:

• Support for unit-level covariance estimation, which allows for more flexible aggregation using the covariance matrix
• Add only_full_horizon option for get_unitdid()

unitdid 0.0.4

New Features:

• Support for unit-level variance estimation, which allows for more flexible aggregation of the variance estimation
• Add allow_negative_var option to allow for negative variance estimation, which used to be automatically trimmed at 0 (v0.0.4.1).

Bug Fixes:

• Measurement error (zz000varcont in the code) is not esimated with weights (#11)

unitdid 0.0.3

New Features:

• Support for first_stage argument for more parametric first stage estimation
• Support for by argument for aggregation

Bug Fixes:

• Bug when data[[yname]] includes NA values
• Bug when variance estimation includes NA values (v0.0.3.1)
• Bug when by does not have a higher category (v0.0.3.2)

unitdid 0.0.2

New Features:

• Support for wname argument for weighted estimation

Bug Fixes:

• Normalization in summary when normalized = FALSE in the model
• Bug when data[[tname]] includes NA values

unitdid 0.0.1

• Initial GitHub submission
