\section{Change in lmridge version 1.2.2 (2023-01-14)}{
\subsection{Improvement}{
  \itemize{
    \item Scaling of \code{X} variables is updated in \code{lmridgeEst()} function. Now ridge regression can be done without scaling of \code{X} variables.
    \item The \code{K}s arranged in order from \code{kest()} function.
    \item Examples for \code{rstats1()}, \code{kest()}, and \code{lmridgeEst()} are updated.
  }

\section{Change in lmridge version 1.2.1 (2021-11-10)}{
\subsection{Improvement}{
  \itemize{
    \item A correction in formula of KAD4 (Dorugade, 2014) from \code{kest()} function  was made.
  }
}
}

\section{Changes in lmridge version 1.2 (2018-08-20)}{
\subsection{Improvements/ Updates}{
  \itemize{
    \item In \code{rstat2()} EDF is chanages to EP.
    \item P-value for ridge F-statistics is computed and displayed in summary statistics.
    \item Information about EP, df1, df2 are added in help file of \code{summary()}.
    \item Appropriate rounding of numbers is done in \code{summary(), lmridge(), vif()} functions.

\section{Changes in lmridge version 1.1 (2018-02-10)}{
  \subsection{Improvements}{
    \itemize{
      \item Arugements of \code{legend()} in all plots are modified for further improvement.
      \item Help file for \code{summary()} and \code{kest()}  is improved.
      \item The \code{y}-axis label removed from \code{bias.plot()} function.
    }
  }
  \subsection{Corrections}{
  \itemize{
    \item Some correction is made in standard error of the intercept term. Therefore, \code{t}-value for intercept (first value of fourth column) and \code{p}-value (first value of fifth column) is updated accordingly.
  \item Correction is made in calculation of CV and GCV methods in \code{kest()} fucntion.
