Functions generated by blocks were introduced by M. Taibleson and G. Weiss in the setting of the one-dimensional torus $T \lbrack TW1 \rbrack$. They showed that these ...

Consider the regression y=f(x̃)+ε , where E(ε|x̃)=0 and the exact functional form of f is unknown, although we do know that f is homogeneous of known degree r. Using a local linear approach, we ...

IN a recent paper, entitled “Notes on Spherical Harmonics” (Proceedings of the Edinburgh Mathematical Society, vol. xxxii., 1914), Dr. John Dougall wrongly claims as new the expansion which he has ...
