  2. Condition index in fish - Wikipedia

    en.wikipedia.org/wiki/Condition_index_in_fish

    The condition index is its actual weight divided by its expected weight, times 100%. A fish of normal weight has a condition index of 100 percent. So if a tarpon, for example, has a condition index of 104 percent, that would mean it is above the normal weight for an average tarpon of that length. If a tarpon has a condition index of 92 percent ...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  4. Voigt profile - Wikipedia

    en.wikipedia.org/wiki/Voigt_profile

    Pseudo-Voigt approximation. The pseudo-Voigt profile (or pseudo-Voigt function) is an approximation of the Voigt profile V (x) using a linear combination of a Gaussian curve G (x) and a Lorentzian curve L (x) instead of their convolution. The pseudo-Voigt function is often used for calculations of experimental spectral line shapes.

  5. Central limit theorem - Wikipedia

    en.wikipedia.org/wiki/Central_limit_theorem

    The scaled sum of a sequence of i.i.d. random variables with finite positive variance converges in distribution to the normal distribution. In probability theory, the central limit theorem (CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution.

  6. Ternary conditional operator - Wikipedia

    en.wikipedia.org/wiki/Ternary_conditional_operator

    The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...

  7. Conditional probability distribution - Wikipedia

    en.wikipedia.org/wiki/Conditional_probability...

    Conditional probability distribution. In probability theory and statistics, the conditional probability distribution is a probability distribution that describes the probability of an outcome given the occurrence of a particular event. Given two jointly distributed random variables and , the conditional probability distribution of given is the ...

    The blisters fill with lymph, break open (3), crust over (4), and finally disappear. Postherpetic neuralgia can sometimes occur due to nerve damage (5). The causative agent for shingles is the varicella zoster virus (VZV)—a double-stranded DNA virus related to the herpes simplex virus .

  9. Confidence interval - Wikipedia

    en.wikipedia.org/wiki/Confidence_interval

    [3] Factors affecting the width of the CI include the sample size, the variability in the sample, and the confidence level. [4] All else being the same, a larger sample produces a narrower confidence interval, greater variability in the sample produces a wider confidence interval, and a higher confidence level produces a wider confidence ...
