# tvReg 0.5.9

* Bug fix in `bwCov` when `bw` is `NULL`.

* Added function `tvCor` to calculate the correlation matrix correspondent to `tvCov`

# tvReg 0.5.8

* Bug fix in `plot`for `tvsure` objects.

* Functionality addition in `tvCov` and `bwCov` to calculate covariance matrices that may vary depending on a random variable.

* Fixing some parameter documentation.

# tvReg 0.5.7

* Bug fix in `forecast` for `tvvar` objects with 1 lag. We thank Michael Wolf for reporting it to us.

# tvReg 0.5.6

* Added package documentation (in "tvReg-package.R", which now also includes data documentation). 

* Changed imports in NAMESPACE. Now only the necessary functions of `plm` are imported (to avoid new compatibility issues between packages `Matrix` and `plm`).

# tvReg 0.5.5

* Updated `RV` dataset and its variables description.
* Fixed bug in `tvAR`and `tvVAR` when `exogen` is only one column.

# tvReg 0.5.4

* Added par(ask=FALSE) at the end of plots.
* Fixed bug in `confint` for objects obtained with `tvFE`
* Fixed bug in `predict` for objects obtained with `tvFE`
* Fixed bug in `tvSURE` for datasets with different name than data
* Added kernel function `Triweight` and make it the default

# tvReg 0.5.3

* Added dates in data `CEES`
* Changed argument `newx` for argument `newdata` in `forecast.tvlm`, `forecast.tvar`, `predict.tvlm` and `predict.tvar`.

# tvReg 0.5.2

* Fixed bug in `tvPLM` and changed the limits of the Epanechnikov kernel.
* Added check for variables size in `tvPLM` when there are NAs.
* Added check for class in `tvAR` main argument.

# tvReg 0.5.1

* Fixed bug in method `tvSURE` when using constraints. Method `confint` works.

# tvReg 0.5.0

* Added methods `tvPLM`, `tvRE` and `tvFE` and methods to fit time-varying coefficients panel data models. Also added their corresponding`confint`, `predict`, `forecast`, `plot`, `summary` and `print` methods.

* Added dataset OECD

* Change all return argument `tvcoef` to `coefficients` to fit the standards of other packages in R

* Allow the user to choose individual plots for each variable in models of class tvlm, tvar or tvplm

* Fix of the bug in R-devel caused by matrix objects now also inheriting from class `array` which caused some problems in some "if" statements

# tvReg 0.4.2

* Added  modified or leave-(2l+1)-out cross-validation for bandwidth selection

* Faster algorithm for the calculation of confidence intervals

* Fix bug in `.tvCov.cv

# tvReg 0.4.1

* Fix bug in `tvGLS.R` for option `est = "ll"`.

* Added a website for the package (with pkgdown).

* Added `README.Rmd` and `index.Rmd`.

* Updated documentation `tvOLS matrix`, `forecast.tvar`, `forecast.tvlm` and
  `forecast.tvsure`.
  
# tvReg 0.4.0

* Removed class `tvlm` from objects of class `tvar`.

* Removed deprecated `CI.tvlm()`, `CI.tvar()`, `CI.tvsure()` and `CI.tvirf()` methods.

* Added `predict.tvlm()`, `predict.tvar()`, `predict.tvsure()` and `predict.tvvar()` methods.

* Added `forecast.tvlm()`, `forecast.tvar()`, `forecast.tvsure()` and `forecast.tvvar()` methods.

* Added `resid.tvlm()`, `resid.tvsure()`, `resid.tvvar()` and `resid.tvirf()` for compatility with R standards.
