BIC

1 8.9
A number that helps choose between statistical models by balancing how well they fit the data and being simple
  • noun
  • /biː aɪ siː/
  • Specialized
: BIC
  • The BIC was preferred over the adjusted BIC because of its better performance with continuous outcomes.
  • BIC value
  • low BIC
  • BIC model

Examples

  • The optimal model for men and women was selected based on a combination of a reasonably low BIC value and theoretical and practical considerations.

    Academic text (2010)
  • A model with a lower BIC value performs better in terms of taking into account both fit and parsimony.

    Academic text (2018)
  • For each model, we examined BIC scores.

    Academic text (2005)
  • So now with let's see with the BIC criterion.

  • A lower BIC indicates a better-fitting model.

    Academic text (2014)
  • Because of the large sample size, the BIC value continued to decrease with an increased number of trajectories.

    Academic text (2010)
  • According to Cohen, Cohen, West, and Aiken (2003), lower AICs and BICs mean that a model is considered to be more likely to be the true model.

    Academic text (2013)
  • The researchers calculated the BIC for each statistical model to determine which one had the best balance between complexity and fit.

  • In their study, the team found that minimizing the BIC helped them select the most appropriate model.

  • To compare the various models, they reported their respective BIC values to find the one that best captured the data without overfitting.

Morphology

BIC = B + I + C

This is an acronym (letters B, I, C); the letters are not meaningful English morphemes and do not allow a learner to derive the definition from component parts.

Etymology

BIC stands for Bayesian Information Criterion, and the last word criterion means 'rule' or 'test'. So, BIC is a rule for choosing models that tries to 'balance' how well a model fits the data with how simple the model is.
