lpirfs 0.2.3

Fixed bug #27.
Added additional output for panel functions. Now, the full plm-objects are returned in addition to summary statistics.
Updated mail address.

lpirfs 0.2.2

Disabled the possibility lags_exog = 0 for functions lp_lin(), lp_nl(), lp_lin_iv() and lp_nl_iv(). Solely contemp_data should be used for exogenous data with contemporaneous impact.
Updated documentation for functions lp_lin(), lp_nl(), lp_lin_iv() and lp_nl_iv() regardings exog_data and lags_exog.

lpirfs 0.2.1

Added the options cumul_mult = FALSE/TRUE for the functions lp_lin_iv and lp_nl_iv. The default is FALSE.
Updated CITATION to use the paper by Adämmer (2019) published in The R Journal.
Updated documentation.

lpirfs 0.2.0

The dependency on the external JST data set has been removed by commenting out the examples for the panel functions. Now, the JST data set has to be downloaded by the user first, before running the examples for the panel functions.

lpirfs 0.1.9

Removed a dependency in the vignette so that it can be build again.

lpirfs 0.1.8

Fixed tests and deprecated functions to be compatible with new dplyr 1.0.0.
Fixed an issue to correctly show summary statistics

lpirfs 0.1.7

Resolved an integer/double issue with an Rcpp function so that the package can also be installed on Oracle Solaris.
Added an option to show how many lags were chosen when an information criterion has been used.

lpirfs 0.1.6

New S3 methods for all main functions to use summary() and plot()
More flexible options for the HAC estimators, such as pre-whitening, sample size adjustment, etc.
New vignette
Updated documentation

lpirfs 0.1.5

Fixed a bug for lp_lin_panel() and lp_nl_panel() regarding the construction of the endogenous and exogenous variables.
Fixed a bug for lp_nl_panel() when using the switching variable.
Fixed a bug for lp_lin_panel() and lp_nl_panel() when a pooling model is specified.
New checks for lp_lin_panel() and lp_nl_panel() to see whether shock variable has been dropped during estimation, potentially because of co-linearity or identification issues.
lp_nl_panel() now returns the (transformed) switching variable as a tibble along with the original data for comparabaility.
Updated documentation.
Updated examples.

lpirfs 0.1.4

Added two functions to estimate linear and nonlinear irfs for panel data.
Added an option to choose whether to use lagged values of the switching variable in nonlinear models.
Added an option to use a dummy approach for the nonlinear models.
Deleted messages about how models are estimated (e.g. with or without exogenous data).
Changed input name in lp_lin_iv() for consistency:

function	old input name	new input name
`lp_lin_iv()`	`twosls`	`use_twosls`

lpirfs 0.1.3

Included an option to conduct 2SLS with lp_lin_iv().
Included an option to set the lag length of the endogenous variables in lp_lin_iv() and lp_nl_iv() to zero.
Deleted the deprecated plot functions plot_lin_irfs() and plot_nl_irfs().
Improved documentation.
Changed input names in lp_lin_iv() and lp_nl_iv() for consistency:

function	old input name	new input name
`lp_lin_iv()`	`instr`	`shock`
`lp_nl_iv()`	`instr`	`shock`

lpirfs 0.1.2

Fixed an error in lp_nl() when lags are chosen by a lag length criterion. Version 0.1.1 chooses lags based on linear instead of nonlinear data.
Removed the dependency on the vars package.
lp_lin() and lp_nl() now allow to include exogenous variables and exogenous variables with contemporaneous impact.
plot_lin_irfs() and plot_nl_irfs() are deprecated and have been replaced by plot_lin() and plot_nl().
Two new functions named lp_lin_iv() and lp_nl_iv() allow to estimate linear and nonlinear impulse responses with identified shocks (instrument variables).
Input names in lp_lin() and lp_nl() have been changed for consistency:

function	old input name	new input name
`lp_lin()`	`lags_lin`	`lags_endog_lin`
`lp_nl()`	`lags_lin`	`lags_endog_lin`
`lp_nl()`	`lags_nl`	`lags_endog_nl`
`lp_nl()`	`hp_filter`	`use_hp`

lpirfs 0.1.1

The dependency on the mFilter package is removed. hp_filter() is now written in C++ to improve efficiency.
A problem with a C++ function is resolved so that the package can also be installed on Oracle Solaris.
Renamed functions:

original name	new name
`lm_function`	`get_resids_ols`
`reduced_var`	`get_mat_chol`
`find_lag_c`	`get_vals_lagcrit`
`newey_west_c`	`newey_west`
`switching_series`	`get_vals_switching`

lpirfs 0.1.0

First CRAN release.

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.
