gini_index_fun

Computes the Gini index (a measure of inequality) for a numeric vector.
Non-finite (<code>NA</code>, <code>NaN</code>, <code>Inf</code>) values are removed prior to computation.
If fewer than two finite values remain, the function returns <code>0</code>.

It leverages the network-like architecture of scientific models together with software quality metrics to identify chains of function calls that are more prone to generating and propagating errors. It operates on tbl_graph objects representing call dependencies between functions (callers and callees) and computes risk scores for individual functions and for paths (sequences of function calls) based on cyclomatic complexity, in-degree and betweenness centrality. The package supports variance-based uncertainty and sensitivity analyses after Puy et al. (2022) <doi:10.18637/jss.v102.i05> to assess how risk scores change under alternative risk definitions.
