Scientific paper

A brief account is given of large-scale structure modelling based on the assumption that the initial perturbations arise from inflation. A recap is made of the implications of inflation for large-scale structure; under the widely applicable slow-roll paradigm inflation adds precisely two extra parameters to the normal scenarios, which can be taken to be the tilt of the density perturbation spectrum and the amplitude of gravitational waves. Some comments are made about the {\it COBE} normalization. A short description is given of an analysis combining cosmic microwave background anisotropy data and large-scale structure data to constrain cosmological parameters, and the case of cold dark matter models with a cosmological constant is used as a specific illustration.
