effect_plot | R Documentation |

This function plots values from effect_draw, the predictive distribution
(under default settings, *posterior* predictive),
for one or more `baggr`

objects.

effect_plot(..., transform = NULL)

`...` |
Object(s) of class baggr. If there is more than one, a comparison will be plotted and names of objects will be used as a plot legend (see examples). |

`transform` |
a transformation to apply to the result, should be an R function;
(this is commonly used when calling |

Under default settings in baggr posterior predictive is obtained. But
`effect_plot`

can also be used for *prior* predictive distributions when
setting `ppd=T`

in baggr. The two outputs work exactly the same, but
labels will change to indicate this difference.

A `ggplot`

object.

effect_draw documents the process of drawing values;
baggr_compare can be used as a shortcut for `effect_plot`

with argument
`compare = "effects"`

# A single effects plot bg1 <- baggr(schools, prior_hypersd = uniform(0, 20)) effect_plot(bg1) # Compare how posterior depends on the prior choice bg2 <- baggr(schools, prior_hypersd = normal(0, 5)) effect_plot("Uniform prior on SD"=bg1, "Normal prior on SD"=bg2) # Compare the priors themselves (ppd=T) bg1_ppd <- baggr(schools, prior_hypersd = uniform(0, 20), ppd=TRUE) bg2_ppd <- baggr(schools, prior_hypersd = normal(0, 5), ppd=TRUE) effect_plot("Uniform prior on SD"=bg1_ppd, "Normal prior on SD"=bg2_ppd)
