View to analyze the response behavior of a regression model

Reported by: gkronber Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.6
Component: Problems.DataAnalysis.Symbolic Version: 3.3.6
Keywords: Cc:

Description

This view should show the change in the output of the model depending on a free variable assuming all other variables in the models are constant. Following information can be gained through such analysis:

  • direction of the influence of a variable on the output (negative or positive impact)
  • the direction and amount that an input variable must be changed to reach a given output value.

Since it often is the case that variables are not independent and have a combined effect on the model output some way of variable set analysis should also be supported.

Ideally it should be possible to visualize the model response of multiple models in one chart.

Tested & reviewed the ResponseFunctionView and except the minor changes in r7122 everything works as expected. Please have a look at those changes and release the ticket afterwards.
