models.
 Residual distribution plots for model performance are now more legible when multiple models are plotted. The styling of plot and axis titles have also been improved (@kevinykuo).
 The defaults of
single_prediction()
are now consistent with breakDown::broken()
. Specifically, baseline
is now 0
by default instead of "Intercept"
. The user can also specify the baseline
and other arguments by passing them to single_prediction
(@kevinykuo, #39). WARNING: Change in the default value of baseline
.
 New
yhat.*
functions help to handle additional parameters to different predict()
functions.
 Updated
CITATION
info
 New dataset
HR
and HRTest

 The
plot.model_performance()
has now show_outliers
parameter. Set it to anything >0 and observations with largest residuals will be presented in the plot. (#34)

 The
single_variable() / variable_response()
function uses predict_function
from explainer
(#17)
 New names for some functions:

is negative

plot_model_performance()

package). Remember to use type='factor'
when playing with factors. (#10)
 Change in the function
