46# Procedure to check if sequence of values in listval follows linear trend
47# adding the same delta on each step.
48#
49# The function does statistical estimation of the mean variation of the
50# values of the sequence, and dispersion, and returns true only if both
51# dispersion and deviation of the mean from expected delta are within
52# specified tolerance.
53#
54# If mean variation differs from expected delta on more than two dispersions,
55# the check fails and procedure raises error with specified message.
56#
57# Otherwise the procedure returns false meaning that more iterations are needed.
58# Note that false is returned in any case if length of listval is less than 3.
