Group‑wise ANOVA simultaneous component analysis for designed omics experiments

Modern omics experiments pertain not only to the measurement of many variables but also follow complex experimental designs where many factors are manipulated at the same time. This data can be conveniently analyzed using multivariate tools like ANOVA-simultaneous component analysis (ASCA) which allows interpretation of the variation induced by the different factors in a principal component analysis fashion. However, while in general only a subset of the measured variables may be related to the problem studied, all variables contribute to the final model and this may hamper interpretatio

TRIGGER-POINT MECHANISM AND CONDITIONAL COMMITMENT: IMPLICATIONS FOR ENTRY, COLLUSION, AND WELFARE

"When fixed, sunk investment costs are high, firms may not have sufficient incentive to enter the market unless future entry is constrained. In this case, the government faces a dilemma between a full commitment and noncommitment of restricted future entry. A way out is to consider a commitment conditional on the realization of the uncertain parameters, such as the trigger-point mechanism (TPM) that sets conditions on current production level, excess capacity, and demand growth under which future entry will be allowed. This article shows that the TPM facilitates the incumbents' collusion but may improve social welfare under certain circumstances."
