1. A method comprising:
obtaining image data of a plurality of features on at least part of at least one region on a substrate;
using the image data to obtain one or more dimensions of at least some features out of the plurality of features;
determining a value of a statistical parameter based on a value of variation of the one or more dimensions and a mean value of the one or more dimensions;
obtaining a probability of defective manufacture of features in dependence on a determined number of defective features in the image data; and
determining, using a hardware computer, a characteristic of one or more processes for manufacturing features on a substrate by deriving a relation between the probability of defective manufacture of features and the value of the statistical parameter.
