Hello SWAT/SWAT-CUP Users,
It is said that the parameter with largest t-statistic value is the most sensitive parameter in SWAT-CUP Sensitivity analysis results. There are negative and positive t-statistic values. Do we take the large absolute value, only the large positive values?
You can refer to the attached diagram to elaborate the answers.
Thank you
Hi Canute:
The t-stat provides a measure of sensitivity (a larger absolute values is more sensitive) and p-value determines the significance of the sensitivity (a value close to zero has more significance).
see page 51 of SWAT-CUP manual http://swat.tamu.edu/media/114860/usermanual_swatcup.pdf

Look at the p-values. Take only parameters whose p-value is less than 0.05. I some times include parameters whose p-value is slightly above the 0.05 threshold
Dear herbert,
i saw different paper where they selected parameters the p value is greater than 0.05. please answer.
