Build regression model from a set of candidate predictor variables by
entering predictors based on chi square statistic, in a stepwise manner
until there is no variable left to enter any more.

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

## Arguments

model |
An object of class `glm` . |

details |
Logical; if `TRUE` , will print the regression result at
each step. |

... |
Other arguments. |

x |
An object of class `blr_step_aic_forward` . |

text_size |
size of the text in the plot. |

## Value

`blr_step_aic_forward`

`"blr_step_aic_forward"`

. An object of class
`"blr_step_aic_forward"`

is a list containing the following components:
