Calculating percentage contribution of a negative component


In one of our models we want to show how much each component has contributed towards the actual value but the values of the component are negative in many cases.
How to show their contribution in such cases?



What modeling technique and problem are you working upon? Please give more details, it is difficult to answer with current information.

Also, if you can show the output (even after anonyizing the variables), that would be great.



It’s UCM we work on. I am sorry I cannot upload the data because of the restrictions. Sir, the Input is decomposed into five components i.e. Seasonality, Trend, Irregularity, Regression and Cyclicality. Now, some of the estimates come negative and we want to show how much each of them is contributing towards the Total actuals value. How do we do that?
