A multifunction tester or MFT is an electronic device used by electricians to test electrical circuits that use the "low" and "extra-low voltages" typically used by consumers in domestic, commercial and agricultural settings.
Testing often requires that the component under test be isolated from the circuit in which they are mounted, as otherwise stray or leakage current paths may distort measurements. In some cases, the voltage from the multimeter may turn active devices on, distorting a measurement, or in extreme cases even damage an element in the circuit being ...
The multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values. The major issue in any discussion of multiple-comparison procedures is the question of the probability of Type I errors.
With respect to FWER control, the Bonferroni correction can be conservative if there are a large number of tests and/or the test statistics are positively correlated. [9] Multiple-testing corrections, including the Bonferroni procedure, increase the probability of Type II errors when null hypotheses are false, i.e., they reduce statistical power.
These figures are lower than a year ago, when rates averaged 7.22% for a 30-year term and 6.56% for a 15-year term. “The 30-year fixed-rate mortgage moved down this week, but not by much," says ...
Multiple testing correction refers to making statistical tests more stringent in order to counteract the problem of multiple testing. The best known such adjustment is the Bonferroni correction , but other methods have been developed.
The Food and Drug Administration has issued warnings about multiple honey packet brands, citing hidden drug ingredients in the product. The big problem, doctors say, is that when you ingest a ...
The British-born director of a tony Washington, D.C., preschool was arrested Tuesday morning on charges that he solicited graphic sex abuse footage of a 9-year-old boy, via the child’s father ...
