       abstract = "We address the task of higher-order derivative evaluation of computer programs that
         contain QR decompositions of tall matrices with full column rank. The approach is a combination of
         univariate Taylor polynomial arithmetic and matrix calculus in the (combined) forward/reverse mode
         of algorithmic differentiation (AD). Explicit algorithms are derived and presented in an accessible
         form.",
