# Visualizing the standard errors

Finally, you want to visualize the standard errors around the model predictions, which will represent the 95 % confidence interval around the estimate of the mean. These are useful for determining how well model can be used to help answer your research question.

Note that the `dragonflies`

data set, `neg_binom_glm_small`

model, `pred_df`

data frame, and `MASS`

and `ggplot2`

libraries have been preloaded.

and adding`se = TRUE`

in the`predict()`

function.
