This is a patch release to reduce the number of packages imported and fix other CRAN errors.

- Bonferroni outlier test (#129)

The following functions will now require the variable names to be enclosed within quotes

`ols_test_bartlett()`

`ols_plot_resid_regressor()`

This is a minor release to fix bugs from breaking changes in recipes package and other enhancements.

- variable selection procedures now return the final model as an
object of class
`lm`

(#81) - data preparation functions of selected plots are now exported to enable end users to create customized plots and to use plotting library of their choice (#86)

This is a patch release to fix minor bugs and improve error messages.

olsrr now throws better error messages keeping in mind beginner and intermediate R users. It is a work in progress and should get better in future releases.

Variable selection procedures based on p values now handle categorical variables in the same way as the procedures based on AIC values.

This is a minor release for bug fixes and API changes.

We have made some changes to the API to make it more user friendly:

- all the variable selection procedures start with
`ols_step_*`

- all the test start with
`ols_test_*`

- all the plots start with
`ols_plot_*`

ols_regress returns error in the presence of interaction terms in the formula (#49)

ols_regress returns error in the presence of interaction terms in the formula (#47)

return current version (#48)

- use
`ols_launch_app()`

to launch a shiny app for building models - save beta coefficients for each independent variable in
`ols_all_subset()`

(#41)

- mismatch in sign of partial and semi partial correlations (#44)
- error in diagnostic panel (#45)
- standardized betas in the presence of interaction terms (#46)

A big thanks goes to (Dr. Kimberly Henry) for identifying bugs and other valuable feedback that helped improve the package.

This is a minor release containing bug fixes.
