For the definition of k-th rank see A208478.
EXAMPLE
For n = 4 the partitions of 4 and the four types of ranks of the partitions of 4 are
----------------------------------------------------------
Partitions First Second Third Fourth
of 4 rank rank rank rank
----------------------------------------------------------
4 4-1 = 3 0-1 = -1 0-1 = -1 0-1 = -1
3+1 3-2 = 1 1-1 = 0 0-1 = -1 0-0 = 0
2+2 2-2 = 0 2-2 = 0 0-0 = 0 0-0 = 0
2+1+1 2-3 = -1 1-1 = 0 1-0 = 1 0-0 = 0
1+1+1+1 1-4 = -3 1-0 = 1 1-0 = 1 1-0 = 1
----------------------------------------------------------
The sums of positive k-th ranks of the partitions of 4 are 4, 1, 2, 1 so the total sum is a(4) = 4+1+2+1 = 8.
