Query: A note on the de la Garza phenomenon for locally optimal designs   The celebrated de la Garza phenomenon states that for a polynomial regression
model of degree $p-1$ any optimal design can be based on at most $p$ design
points. In a remarkable paper, Yang [Ann. Statist. 38 (2010) 2499--2524] showed
that this phenomenon exists in many locally optimal design problems for
nonlinear models. In the present note, we present a different view point on
these findings using results about moment theory and Chebyshev systems. In
particular, we show that this phenomenon occurs in an even larger class of
models than considered so far.
