  2. Best linear unbiased prediction - Wikipedia

    en.wikipedia.org/wiki/Best_linear_unbiased...

    Best linear unbiased predictions" (BLUPs) of random effects are similar to best linear unbiased estimates (BLUEs) (see Gauss–Markov theorem) of fixed effects. The distinction arises because it is conventional to talk about estimating fixed effects but about predicting random effects, but the two terms are otherwise equivalent.

  3. Dice tower - Wikipedia

    en.wikipedia.org/wiki/Dice_tower

    Dice towers have been used since at least the fourth century, in an attempt to ensure that dice roll outcomes were random. [1] The Vettweiss-Froitzheim Dice Tower is a surviving example, used by Romans in Germany; it has essentially the same design as modern examples, with internal baffles to force the dice to rotate more randomly.

  4. Positive and negative predictive values - Wikipedia

    en.wikipedia.org/wiki/Positive_and_negative...

    The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.

  5. Conditional expectation - Wikipedia

    en.wikipedia.org/wiki/Conditional_expectation

    In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value evaluated with respect to the conditional probability distribution. If the random variable can take on only a finite number of values, the "conditions" are that the variable can only take on a subset of ...

    On the contrary, they “are in deep value territory.” Since this statement, Roblox (NYSE:RBLX) stock has corrected by 56% to current levels below $42. It indeed seems now that RBLX stock is in ...

  7. Law of total expectation - Wikipedia

    en.wikipedia.org/wiki/Law_of_total_expectation

    The proposition in probability theory known as the law of total expectation, [1] the law of iterated expectations [2] (LIE), Adam's law, [3] the tower rule, [4] and the smoothing theorem, [5] among other names, states that if is a random variable whose expected value ⁡ is defined, and is any random variable on the same probability space, then

  8. D6 System - Wikipedia

    en.wikipedia.org/wiki/D6_System

    The value of each die is totalled and the pips are added to the die roll to get a total. This total along with any GM or system imposed modifiers is compared against a target difficulty number. To perform an opposed roll action, the two parties involved (usually the player and a gamemaster controlled character) both roll their appropriate ...

  9. Brier score - Wikipedia

    en.wikipedia.org/wiki/Brier_score

    A skill score for a given underlying score is an offset and (negatively-) scaled variant of the underlying score such that a skill score value of zero means that the score for the predictions is merely as good as that of a set of baseline or reference or default predictions, while a skill score value of one (100%) represents the best possible ...
