The function considers the counts per segment and uses them sequentially until
d positive counts
are obtained or until all
s segments have been considered. If we assume that
u counts are used (of
which some may be zero) then
the visual fast count estimator is the mean over the
u counts multiplied by
s. This function is used
GVFCMOM to obtain the method of moments VFC estimator - which has reduced bias compared to the
raw VFC estimator.
GVFC(counts, s, d)
Vector of length s that contains a count for each segment
Number of segments
Number of positive segment counts needed before counting stops
The raw VFC estimate of the segment mean
