Simultaneous Quantile Regression

  • Developed a Bayesian Nonparametric approach for simultaneously estimating nonlinear quantile regression curves at multiple quantile levels using Quantile pyramids
  • Implemented efficient C++ code to execute the methodology, utilizing Markov Chain Monte Carlo with Metropolis-Hastings steps [code]
