Scaling of

`X`

variables is updated in`lmridgeEst()`

function. Now ridge regression can be done without scaling of`X`

variables.The

`K`

s arranged in order from`kest()`

function.Examples for

`rstats1()`

,`kest()`

, and`lmridgeEst()`

are updated.

A correction in formula of KAD4 (Dorugade, 2014) from

`kest()`

function was made.

In

`rstat2()`

EDF is chanages to EP.P-value for ridge F-statistics is computed and displayed in summary statistics.

Information about EP, df1, df2 are added in help file of

`summary()`

.Appropriate rounding of numbers is done in

`summary(), lmridge(), vif()`

functions.

Arugements of

`legend()`

in all plots are modified for further improvement.Help file for

`summary()`

and`kest()`

is improved.The

`y`

-axis label removed from`bias.plot()`

function.

Some correction is made in standard error of the intercept term. Therefore,

`t`

-value for intercept (first value of fourth column) and`p`

-value (first value of fifth column) is updated accordingly.Correction is made in calculation of CV and GCV methods in

`kest()`

fucntion.
