Strictly speaking, “standard” CDM usually refers to the parameter choice (Formula presented) and (Formula presented); while such a model yields a better shape for (Formula presented) than does an (Formula presented) model with (Formula presented), the fit to the data is still poor

Another fix for the amplitude problem is to introduce a small tilt to the primordial power spectrum, (Formula presented), with (Formula presented). In the models of Fig. 11, we have assumed a scale-invariant primordial spectrum with (Formula presented), but inflationary models typically predict small deviations from this, with (Formula presented) less than unity in models with a single scalar field; see, e.g
