why can't i use aNOVA in an experiment that has 400,000 measurements of a single twin? how is paired observation tested in twin studies how many observations are there at each genomic location? why does the genetic variation occur in a twin study which is true of equivalence testing for twins? how many sets of measurements are available why is the general variation at each locus not significant how many sets of twins how many measurements between twins how many measurements are there for the equivalence test how many measurements in twins how to test for genetic variation how do i test for variation between twins? how many measurements in a set of twins how does equivalence testing work how many observations are made for each twin if the genetic variation is between twins is greater the equivalence test should be done how do you test equivalence of twins how many measurements are made of twins how many sets of data should you have to compare twins
