  2. Pivot table - Wikipedia

    en.wikipedia.org/wiki/Pivot_table

    Excel pivot tables include the feature to directly query an online analytical processing (OLAP) server for retrieving data instead of getting the data from an Excel spreadsheet. On this configuration, a pivot table is a simple client of an OLAP server.

  3. Conditional probability distribution - Wikipedia

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

    If the conditional distribution of given is a continuous distribution, then its probability density function is known as the conditional density function. [1] The properties of a conditional distribution, such as the moments , are often referred to by corresponding names such as the conditional mean and conditional variance .

  4. Condition number - Wikipedia

    en.wikipedia.org/wiki/Condition_number

    Condition numbers can also be defined for nonlinear functions, and can be computed using calculus.The condition number varies with the point; in some cases one can use the maximum (or supremum) condition number over the domain of the function or domain of the question as an overall condition number, while in other cases the condition number at a particular point is of more interest.

  5. Law of total variance - Wikipedia

    en.wikipedia.org/wiki/Law_of_total_variance

    Note that the conditional expected value ⁡ is a random variable in its own right, whose value depends on the value of . Notice that the conditional expected value of given the event = is a function of (this is where adherence to the conventional and rigidly case-sensitive notation of probability theory becomes important!).

  6. Marginal distribution - Wikipedia

    en.wikipedia.org/wiki/Marginal_distribution

    Given a known joint distribution of two discrete random variables, say, X and Y, the marginal distribution of either variable – X for example – is the probability distribution of X when the values of Y are not taken into consideration.

    However, note that performance suffers when there are more than 100 alternatives. Placing common values earlier in the list of cases can cause the function to execute significantly faster. For each case, either side of the equals sign "=" can be a simple string, a call to a parser function (including #expr to evaulate expressions), or a ...

  8. Conditional probability - Wikipedia

    en.wikipedia.org/wiki/Conditional_probability

    In probability theory, conditional probability is a measure of the probability of an event occurring, ... we see that it is a function of two variables, x and A.

  9. Table (information) - Wikipedia

    en.wikipedia.org/wiki/Table_(information)

    The summary information consists of subtotals that are combined from previous rows within the same column. The concept of dimension is also a part of basic terminology. [ 7 ] Any "simple" table can be represented as a "multi-dimensional" table by normalizing the data values into ordered hierarchies .
