Exploratory Experiments
Philosophers of experiment have acknowledged that experiments are often more than mere hypothesis-tests, once thought to be an experiment’s exclusive calling. Drawing on examples from contemporary biology, I make an additional amendment to our understanding of experiment by examining the way that ‘wide’ instrumentation can, for reasons of efficiency, lead scientists away from traditional hypoth...
متن کاملOptimal designs for conjoint experiments
In conjoint experiments, each respondent receives a set of profiles to rate. Sometimes, the profiles are expensive prototypes that respondents have to test before rating them. Designing these experiments involves determining how many and which profiles each respondent has to rate and how many respondents are needed. To that end, the set of profiles offered to a respondent is treated as a separa...
متن کاملCook’s Collage: Two Exploratory Designs
Gathered from observations and studies of how people busily manage tasks amidst distractions, forgetfulness, and multitasking in their homes, we identify two common cooking predicaments. We introduce Cook’s Collage, a context-aware system that passively displays recent activities. We posit that a cook, by glancing at these visual cues, can easily resume his task following an interruption when h...
متن کاملOptimal Factorial Designs for Cdna Microarray Experiments
We consider cDNA microarray experiments when the cell populations have a factorial structure, and investigate the problem of their optimal designing under a baseline parametrization where the objects of interest differ from those under the more common orthogonal parametrization. First, analytical results are given for the 2× 2 factorial. Since practical applications often involve a more complex...
متن کاملCage allocation designs for rodent carcinogenicity experiments.
Cage allocation designs for rodent carcinogenicity experiments are discussed and presented with the goal of avoiding dosage group biases related to cage location. Considerations in selecting a cage design are first discussed in general terms. Specific designs are presented for use in experiments involving three, four, and five dose groups and with one, four, and five rodents per cage. Prioritie...
