Trend Departure Index Results for the RESTORE Trend Analysis and Streamflow Alterations studies
Trend Departure Index (TDI) is computed as: (number of quantiles for which the trend result departs from the result for the associated reference site)  /  (total number of quantiles). In a Quantile-Kendall analysis for the annual time frame, the denominator, or total number of quantiles, is 365. 
TDI varies from 0 to …
