# ARDL 0.2.1

### New features

• The bounds_f_test and bounds_t_test functions now have a new returned value PSS2001parameters, if alpha is one of the 0.1, 0.05, 0.025 or 0.01, exact = FALSE and k <= 10. These are the critical value bounds presented in Pesaran et al. (2001) but are less precise. Previously, only these were reported in parameters.
e.g. In the following marginal case, according to the critical values of Pesaran et al. (2001), H0 is rejected but according to the p-value is not.

m1 <- uecm(w ~ Prod + UR + Wedge + Union | D7475 + D7579, order = c(5, 1, 5, 5, 5), data = PSS2001, start = c(1972, 01))
btt <- bounds_t_test(m1, case = 3, alpha = 0.05)}
btt$$tab btt$$PSS2001parameters

### Documentation update

• Added BugReports in the DESCRIPTION.

• Updated the references in README and CITATION.

### Bug fix

• multipliers() was giving an error when trying to estimate short-run and interim multipliers using a model without a constant term.

### New data

• Added the data used in Pesaran et al. (2001)

### Minor changes

• Added dependency on R >= 3.5.0 because serialized objects in serialize/load version 3 cannot be read in older versions of R. File(s) containing such objects: ‘ARDL/data/PSS2001.rda’

# ARDL 0.2.0

### Documentation update

• Add DOI and references of the publication where the package is used and successfully replicates the results of the methodology it implements, in the DESCRIPTION and README.Rmd files.

• Properly changed the citation info in the CITATION and ardl-package.Rfiles.

# ARDL 0.1.1

### New features

• The multipliers() function now supports the calculation of short-run and interim multipliers.

### Documentation improvements

• Corrected the example about the search_type argument in the help file of auto_ardl().

• Minor correction in the help file of auto_ardl().

• Corrected the mathematical formula of the Long-Run multipliers in the help file of multipliers().

• Corrected the mathematical formula of the bounds F-test in the help file of bounds_f_test().

• Added the mathematical formulas of the short-run and interim multipliers in the help file of multipliers().

• Properly changed the citation info in the CITATION, ardl-package.R and
DESCRIPTION files.

• Changed the designer’s contact info in the logo.
