  • Migration Analysis: Combining Approaches for Better Results

    variations on the theme, migration models generally fall into one of three categories: base-period (BP) models, average-loss-rate (ALR) models and Markov models. Base-period models.One of the most common migration modeling methodologies, particularly among institutions with less than 5 billion in assets, is the BP model. Reasons for

  • M.A.R.C.: AN ACTUARIAL MODEL FOR CREDIT RISK

    M.A.R.C. (Actuarial Model for Credit Risk). With the M.A.R.C. model we want to propose a general scheme useful for applying risk theory methods to credit portfolios. To this purpose we have built up a model based on stochastic simulation (Monte Carlo method); this technique gives to the model the necessary flexibility.

  • MIGRATION MATRICES, Migration Matrices and Cumulative .

    Migration Matrices and Cumulative Default Probabilities A migration matrix is a squared matrix with initial credit state, or rating, in rows and final credit state in columns. There is usually an additional column, called "WR," for firms existing at the beginning of the period and whose rating was withdrawn within the period.

    Highlights A mathematical model is developed for a down-hole oil–water separation hydrocyclone. The proposed model is based on the prediction of the flow field of the dispersed phase. The separation efficiency is determined based on droplet trajectory analysis. The results show that the model can predict the efficiency of a down-hole hydrocyclone.
