Estimation of Different Quantile Related Models // Estimation of different quantile models, at the moment only Conditional autoregressive value at risk (CAViaR) proposed by Engle Manganelli (2004) doi:10.1198/073500104000000370 with also the specification proposed in Huang et al. (2009) doi:10.1016/j.eneco.2008.12.006 and it's multivariate extension, Multi-variate multi-quantile CAViaR (MVMQ-CAViaR) proposed by White et al. (2015) doi:10.1016/j.jeconom.2015.02.004 are available, however, in further updates, other models and extensions will be included.
