This proposed methodology is based on a combination of qualitative and quantitative factors through an expert-based model approach. More specifically, our methodology relies on the determination of an anchor rating through the use of a partial least squares model combined with variable importance projection (PLS-VIP) that takes into account, for each sovereign, a set of key performance indicators (KPIs) distributed across three pillars and eight sub-pillars. In a second step, we apply a series of qualitative adjustments to the anchor rating for each of the sub-pillars to include in the analytical process all those qualitative factors that are not part of the model.
