Selection effect occurs when a subset of a population is more likely to be included in a sample or study than others due to some bias or limitations. In this case, dwarf elliptical galaxies are not included in catalogues of nearby galaxies, which could be due to their small size and low brightness that make them more difficult to detect and classify. This selection effect could lead to biases and incomplete understanding of the distribution and properties of galaxies in the nearby universe.
