Detection of modality: Number of realisations out of 100 in which the modality of the density is correctly identified.

The upper row refers to modes, the lower row to bumps. Modes and bumps are counted on the indicated interval. For test cases 14 and 15, the semiparametric estimators allow for logarithmic boundary terms at any boundary point. The best method is indicated in bold. For test case 8, the diffusion estimators give reasonable density estimates in most realisations but are unstable in some realisations. See S3 Appendix for further explanation.
