start

beginning balance

end

ending balance

endtime

end time of comparison

Details

I=end-start-\sum_{k=1}^ncf_k

i^{dw}=\frac{I}{start*endtime-\sum_{k=1}^ncf_k*(endtime-times_k)}

Value

The dollar weighted yield.

Note

Time of comparison (endtime) must be larger than any number in vector of cash flow times.

Length of cashflow vector and times vector must be equal.
