Link analysis refers to a set of procedures for identifying relationships between items in a dataset. These relationships can be categorized according to different types of relations, such as co-occurrence, sequential occurrence, or causality. The identified relations can then be used to generate new insights from the data or to support decision-making processes. in other words, link analysis is a way of understanding how things are related to each other.
Link Analysis vs. Cluster Analysis vs. Factor Analysis
Link analysis can be contrasted with other methods for analyzing data, such as cluster analysis or factor analysis. Cluster analysis groups items together based on similarity, while factor analysis identifies underlying relationships between variables. Link analysis is unique that it focuses on relationships between items rather than similarities or underlying causes.
