f_logistic_auc_unbalanced {collinear}

AUC of Binomial GLM with Logit Link and Case Weights

Description

Fits a quasibinomial GLM model y ~ x with case weights when y is an unbalanced binary response with values 0 and 1 and x is numeric. It uses the function case_weights() to weight 0s and 1s according to their frequency within y.

Usage

f_logistic_auc_unbalanced(x, y, df)

Arguments

x

(required, character string) name of the predictor variable.

y

(required, character string) name of the binary response variable.

df

(required, data frame) data frame with the columns 'x' and 'y'.

Value

Area Under the Curve

Examples

data(vi)

#subset to limit example run time
vi <- vi[1:1000, ]

f_logistic_auc_unbalanced(
  x = "growing_season_length", #predictor
  y = "vi_binary",             #binary response
  df = vi
)
