Back to continue our discussion on systems monitoring.
For systems monitorin,g we bring in time indices: k,k-1,k-2
Instead of using IV, now we use cosine to express the state of vectors:
Then the systems successional trends are defined as present cosine over the previous cosine values:
Trend(i,k) = cos(i,k)/cos(i,k-1)
The expectation of the trend values are 1:
Trend(i,k)= cos(i,k)/cos(i,k-1) =1, where i=1,2,...17,means that there is no change
Trend(i,k) = cos(i,k) / cos(i,k-1) >1, where i=1,2,...17,means that the given fund is increasing, but
Trend(i,k)= cos(i,k) / cos(i,k-1) <1, where i=1,2,...17,means that the given fund is decreasing.
