Peak thick tail test
WebDec 15, 2014 · You can get a sense of this from a histogram by looking at how tall the peak on the left is: the taller the peak, the more p-values are close to 0 and therefore significant. Similarly, the “depth” of the histogram on the right side … WebTo fix: a) Confirm that the correct liner is being used. If you suspect dead volume, try using a smaller internal diameter liner, or incorporate an injection pressure-pulse into your instrument program. b) Use an electronic leak detector to locate leaks. c) Remove the column from the injection port, trim, and reinstall.

In probability theory, heavy-tailed distributions are probability distributions whose tails are not exponentially bounded: that is, they have heavier tails than the exponential distribution. In many applications it is the right tail of the distribution that is of interest, but a distribution may have a heavy left tail, or both tails may be heavy. There are three important subclasses of heavy-tailed distributions: the fat-tailed distributions, the long … WebA one tailed test does not leave more room to conclude that the alternative hypothesis is true.
