I am trying for local sensitivity analysis using “ODELocalSensitivityProblem” from [http://docs.juliadiffeq.org/latest/analysis/sensitivity.html#Example-solving-an-ODELocalSensitivityProblem-1](http://docs.juliadiffeq.org/latest/analysis/sensitivity.html#Example-solving-an-ODELocalSensitivityProblem-1). However, how do I set for parameters boundary? Ile, let say parameter are changed from -10% to +10%.

Local sensitivity analysis is derivative-based and so it doesn’t sample. It just calculates the derivative at chosen parameters.
