Mm. Gabr et Ts. Rao, ON THE ESTIMATION OF BISPECTRAL DENSITY-FUNCTION IN THE CASE OF RANDOMLY MISSING OBSERVATIONS, IEEE transactions on signal processing, 42(1), 1994, pp. 211-216
The estimation of the bispectral density function of a stationary stoc
hastic process R hen some observations are missing according to a poin
t binomial distribution is considered in the paper. The existence of t
he bispectrum, and its estimation are considered. The methods are illu
strated with simulated examples.
