PAGFL 1.1.2 (development version)

• Fixed backwards compatibility issue with the generic functions fitted and resid
• Bugfix when passing index variables and an empty formula y ~ . for tv_pagfl and grouped_tv_plm
• Improved documentation
• Changed x-axis label in the plot produced by calling summary() of a tvpagfl object
• Bugfix in the plot produced by calling fitted() and passing a character time-index variable
• Added the current algorithm iteration and tuning parameter as a progress counter to the console if option verbose is selected
• Changed the IC selecting the best fitting tuning parameter for the tv_pagfl and grouped_tv_plm procedures to include the logarithmic mean squared error as the fitness term

PAGFL 1.1.1

• Introduction of grouped_plm and grouped_tv_plm to estimate grouped (time-varying) panel data models given an exogenous group structure
• Remove warm-starts when iterating across different tuning parameters
• Small efficiency upgrades
• More extensive unit testing
• Improved documentation
• Small updates to generic methods

PAGFL 1.1.0

• Introduction of the time-varying PAGFL tv_pagfl
• Introduction of s3 methods (summary(), coef(), fitted(), resid()) for the output of pagfl and tv_pagfl
• Change of the user interface to formula objects
• Implementation of unit testing
• Renamed functions to be consistently snake case
• Support for unordered and/ or unbalanced panel data sets via index
• Possibility to estimate a mix of time-constant and time-varying coefficients in the same panel data model (const_coef)
• Added row and column names to the estimation output
• Maximum within-group heterogeneity group_tol set to a machine inaccuracy value
• Improved documentation, checks, and error/warning messages
• Enabled 64bit C++ compiler to support large datasets
• Improvements to efficiency and numerical stability
• Bugfixes

PAGFL 1.0.1

• Patch to fix freak bug in the M1Mac build

PAGFL 1.0.0

• Initial CRAN submission.
