Build regression model from a set of candidate predictor variables by entering and removing predictors based on akaike information criterion, in a stepwise manner until there is no variable left to enter or remove any more.

blr_step_aic_both(model, details = FALSE, ...) # S3 method for blr_step_aic_both plot(x, text_size = 3, ...)

model | An object of class |
---|---|

details | Logical; if |

... | Other arguments. |

x | An object of class |

text_size | size of the text in the plot. |

`blr_step_aic_both`

returns an object of class `"blr_step_aic_both"`

.
An object of class `"blr_step_aic_both"`

is a list containing the
following components:

model with the least AIC; an object of class `glm`

candidate predictor variables

variables added/removed from the model

addition/deletion

akaike information criteria

bayesian information criteria

deviances

total number of steps
