S4 removed the diagram and changed the title to "Path Coefficients". They also updated the content by making it a definition for Path Coefficients. They cited the redundancy of having two of the same diagrams as their reasoning. They also changed the concept's parent node from "S Wright's Guinea Pigs and the 'First link of Causality and Probability'" to "The path diagram for inheritance of fur color in guinea pigs" to improve the hierarchical organization.
