  2. Transactional net margin method - Wikipedia

    en.wikipedia.org/wiki/Transactional_net_margin...

    The transactional net margin method (TNMM) in transfer pricing compares the net profit margin of a taxpayer arising from a non-arm's length transaction with the net profit margins realized by arm's length parties from similar transactions; and examines the net profit margin relative to an appropriate base such as costs, sales or assets.

    en.wikipedia.org/wiki/Jamshidian's_trick

    Jamshidian's trick is a technique for one-factor asset price models, which re-expresses an option on a portfolio of assets as a portfolio of options. It was developed by Farshid Jamshidian in 1989. The trick relies on the following simple, but very useful mathematical observation.

  4. Block matrix pseudoinverse - Wikipedia

    en.wikipedia.org/wiki/Block_matrix_pseudoinverse

    In mathematics, a block matrix pseudoinverse is a formula for the pseudoinverse of a partitioned matrix. This is useful for decomposing or approximating many algorithms updating parameters in signal processing , which are based on the least squares method.

  5. Block LU decomposition - Wikipedia

    en.wikipedia.org/wiki/Block_LU_decomposition

    In linear algebra, a Block LU decomposition is a matrix decomposition of a block matrix into a lower block triangular matrix L and an upper block triangular matrix U. This decomposition is used in numerical analysis to reduce the complexity of the block matrix formula.

  6. Bayesian-optimal pricing - Wikipedia

    en.wikipedia.org/wiki/Bayesian-optimal_pricing

    Bayesian-optimal pricing (BO pricing) is a kind of algorithmic pricing in which a seller determines the sell-prices based on probabilistic assumptions on the valuations of the buyers. It is a simple kind of a Bayesian-optimal mechanism , in which the price is determined in advance without collecting actual buyers' bids.

    en.wikipedia.org/wiki/Block_code

    The block length of a block code is the number of symbols in a block. Hence, the elements c {\displaystyle c} of Σ n {\displaystyle \Sigma ^{n}} are strings of length n {\displaystyle n} and correspond to blocks that may be received by the receiver.

  9. Funds transfer pricing - Wikipedia

    en.wikipedia.org/wiki/Funds_Transfer_Pricing

    A given fund transfer price will impact the measured performance of business units based on whether such business units are short of funds or have an excess of funds. The key variable which should be considered for setting the fund transfer price is the strategy of the financial institution (i.e. corporate strategy).
