They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. Automobile electrical circuit breaker with resettable switchĪutomotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. The top metal surfaces can be tested using multimeter probes.

ATO ATC FULL
When using full matching or subclassification, make sure you select the correct estimand and use the resulting weights correctly as described in the MatchIt vignette on estimating effects (i.e., rather than estimating separate effects within each subclass).This article includes a list of general references, but it lacks sufficient corresponding inline citations. All weighting methods can be adapted to the ATT, ATC, or ATE, but most matching methods are restricted in the estimand they target. If you are using MatchIt or WeightIt in R you can select the estimand you want for each method if available.
ATO: pair matching w/ a caliper, cardinality matching, coarsened exact matching, overlap weighting, trimming. ATE: full matching, subclassification, inverse probability weighting. ATT and ATC: pair matching w/o a caliper, full matching, subclassification, weighting by the odds. Literature on precision medicine and individual treatment rules may be helpful there.ĭifferent methods target different estimands. The more nuanced question of "How can doctors optimally prescribe treatment to optimize results?" is a different question that is not answerable in the framework of the four main estimands. This would be useful for evaluating whether the medicine should be withheld from those receiving it (i.e., because doctors are not prescribing it well). The second question, "How well does the medicine help the people they treated?" is definitely an ATT question. The ATO, ATT, and ATC assume there is already a stable mechanism for treatment prescription in the population. If you want to ask "Would the medicine be effective for those who not currently being prescribed it?" then you want the ATC. If you want to ask "Is the medicine effective for those who are already being prescribed it?" then you want the ATT. If you want to ask, "Should this medicine be unilaterally recommended over a competing medicine?" then you want the ATE (e.g., comparing name-brand to generic). This is typically the question small randomized control trials seek to answer. If you want to ask whether it is effective for anyone, you are engaging in "treatment effect discovery", discussed in Mao et al (2018), for which the ATO is best suited because its estimates are precise and less susceptible to bias. It might be effective for some and not others. The question of "Is this new medicine effective?" is too broad to be of much use. ATO: the effect of a treatment for those under equipoise, i.e., total uncertainty about which treatment is more effective. 
unilaterally implementing another useful when you have no information for making a more nuanced decision ATE: the effect of unilaterally implementing one policy vs.ATC: the effect of expanding treatment to those not receiving it or exposing a pollutant to those not exposed.ATT: the effect of withholding treatment, preventing an exposure, or continuing to implement an experimental program.I'll briefly summarize when each estimand would be substantively useful. ( Edit: Here is the arxiv version.) I also discuss the motivation for different estimands in this answer.

I'm writing a paper on this, and I'll update with a link when it's posted.
