Does this fit??

I would also have suggested addmission of weakness, but I can't see it fitting into the English text. Lost in the translation perhaps??

I don't mean to suggest this as your answer but my interpretation of the descriptive word "zwaktebod" for the concept:

imputation (im·pu·ta·tion) (im²pu-ta¢sh[schwa]n) the use of statistical methods to estimate missing values from available values when data are missing, e.g., due to lack of response to a survey.

This is an estimation of the 'weight' that non-responders in an experiment might have. An estimated guess or a better synonym is perhaps on the order here.
Good luck.

Here I looked op the word bod:

bod
1. offer, proposal, suggestion

zwakte is weakness

I’ve heard ‘An anemic solution’ to describe the pitfalls and statistical weaknesses of some research but this is a style question you could better answer.

The reference for \'imputation\'

and don\'t forget the comma before which:
\'a specific cortical location, which ...\'

Internet reference:
No pity for the feeble attempt of KMFDM

I have the feeling that "zwaktebod" is meant here as something that is not quite good enough. It is used because there is nothing better. Would that be a way of looking at it?
