PSTR 2.0.0 ‘Green Panel’
Breaking changes
- The internal architecture is fully refactored to an R6 design.
- Direct access to internal slots is no longer supported.
- Users relying on previous S3-style behaviour may need to update
their code.
New features
- The
PSTR class now follows an R6 design with reference
semantics.
- The main modelling steps are implemented as class methods.
- Exported wrapper functions remain available for backward
compatibility.
- The command line output is redesigned using the
cli
package.
- The print layout is modernised using
knitr::kable.
- Separate print views are available for summary, tests, estimation,
and evaluation.
- Internal getters and setters are added to support a clean R6
workflow.
Improvements
- Evaluation and bootstrap routines are rewritten under the R6
structure.
- Result objects are stored with consistent naming (
tv,
ht, wcb_tv, wcb_ht).
- Numerical robustness is improved in near-singular matrix inversion
cases.
- An SVD-based pseudoinverse is used when necessary.
- Bootstrap routines use deep cloning to avoid overwriting the
original object.
- Internal print helpers are reorganised into dedicated private
methods.

New Features in PSTR
1.2.1 ‘Orange Panel’

New Features in PSTR
1.2.0 ‘Orange Panel’
- New function “plot_response” which use the ggplot2 and plotly
packages to plot the curve or surface of the expected response
(contribution) against some variable and the transition variable.
- The estimation function “EstPSTR” will return the estimated
time-invariante individule effects.
- The width of the separating lines in printing the results can adjust
itself automatically to fit the width of the console.
- Rewrite the “version” function.
New Features in PSTR 1.1.0
‘Red Panel’
- Better documentation.
- In the function “EstPSTR”, now the initial value for “gamma” is
allowed. The user can freely choose either “gamma” or “delta” to input
for the estimation.
- Estimation of a linear panel regression model with fixed
effects.
- The initial values can now be chosen automatically and will be
returned after estimation.
- New function “plot_transition” which use the ggplot2 package to plot
the estimated transition function.
- The package ggplot2 imported.
- A new data set “sunspot” included.
- Some bugs fixed.
New Featurs in PSTR 1.0.1
- All the functions
- Documetation including README, LICENSE and etc.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
