In this article, we propose two important measures, quantile correlation (QCOR) and quantile partial correlation (QPCOR). We then apply them to quantile autoregressive (QAR) models, and introduce two ...

Autocorrelation can be used for analyzing many types of data. In investments, autocorrelation is part of the technical analysis toolkit used to assess the predictability of asset returns.
