Exact mean and covariance formulas after diagonal transformations of a multivariate normal

Rebecca Morrison, Estelle Basor

Consider $X \sim N (0, I^£)$ and $Y = (f_{1} (X_{1}), f_{2} (X_{2}), \dots, f_{d} (X_{d}))$ . We call this a diagonal transformation of a mul…

Analytic solutions to nonlinear ODEs via spectral power series

Estelle Basor, Rebecca Morrison

Solutions to most nonlinear ordinary differential equations (ODEs) rely on numerical solvers, but this gives little insight into the nature of the trajectories and is relatively ex…
