Figure 4.

Bayesian networks between six latent variables based on two score-based (4a: Hill Climbing and 4b: Tabu) and two hybrid (4c: Max-Min Hill Climbing and 4d: General 2-Phase Restricted Maximization) algorithms. The quality of the structure was evaluated by bootstrap resampling and model averaging across 500 replications. Labels of the edges refer to the strength and direction (parenthesis) which measure the confidence of the directed edge. The strength indicates the frequency of the edge is present and the direction measures the frequency of the direction conditioned on the presence of edge. BIC: Bayesian information criterion score. BGe: Bayesian Gaussian equivalent score. Msr: morphological salt response; Iss: ionic components of salt stress; Grm: grain morphology; Yid: yield; Mrp: morphology; Flt: flowering time.
