FACTORIAL DESIGNS Two Factor Factorial Designs

4.1 Two Factor Factorial Designs A two-factor factorial design is an experimental design in which data is collected for all possible combinations of the levels of the two factors of interest. If equal sample sizes are taken for each of the possible factor combinations then the design is a balanced two-factor factorial design.

LOF: Identifying Density-Based Local Outliers

The outlier factor is local in the sense that only a restricted neighborhood of each object is taken into account. Our approach is loosely related to density-based clustering. However, we do not require any explicit or implicit no-tion of clusters for our method. Specifically, our …
