lifetime models for probability of default -凯发k8网页登录

estimate loss reserves based on lifetime analysis

develop and validate lifetime models for probability of default (pd) based on a lifetime analysis conditional on macroeconomic scenarios. calculate the estimated loss reserves using expected credit loss (ecl) calculator.

functions

create specified lifetime pd model object type
compute conditional pd
compute cumulative lifetime pd, marginal pd, and survival probability
compute auroc and roc data
plot roc curve
compute rmse of predicted and observed pds on grouped data
plot observed default rates compared to predicted pds on grouped data
discard residual information of underlying cox model
compute the lifetime ecl at individual or portfolio level

objects

create logistic model object for lifetime probability of default
create probit model object for lifetime probability of default
create cox model object for lifetime probability of default
create customlifetimepdmodel object for lifetime probability of default

topics


  • estimate loss reserves based on a lifetime analysis conditional on macroeconomic scenarios.


  • this example shows how to perform basic model validation on a lifetime probability of default (pd) model by viewing the fitted model, estimated coefficients, and p-values.


  • this example shows how to compare a new logistic model for lifetime pd against a "champion" model.


  • this example shows how to compare three lifetime pd models using cross-validation.


  • this example shows how to perform expected credit loss (ecl) computations with portfolioecl using simulated loan data, macro scenario data, and an existing lifetime probability of default (pd) model.


  • this example shows some differences between discrimination and calibration metrics for the validation of probability of default (pd) models.


  • this example shows how to work with consumer (retail) credit panel data to visualize observed probabilities of default (pds) at different levels.


  • train a credit risk for probability of default (pd) prediction using a deep neural network.


  • this example shows how to use customlifetimepdmodel to create a lifetime model for the probability of default.


  • this example shows how to fit a decision tree model for credit scoring and then use the customlifetimepdmodel object to create a lifetime model for probability of default.

  • incorporate macroeconomic scenario projections in loan portfolio ecl calculations

    this example shows how to generate macroeconomic scenarios and perform expected credit loss (ecl) calculations for a portfolio of loans.
