  2. Shift-share analysis - Wikipedia

    en.wikipedia.org/wiki/Shift-share_analysis

    Shift-share analysts sometimes use different labels for the three effects, although the calculations are the same. National growth effect may be referred to as national share. [4] [5] Industry mix effect may be referred to as proportional shift. [5] Local share effect may be referred to as differential shift, [3] regional shift, [4] or ...

  3. Computation of cyclic redundancy checks - Wikipedia

    Various CRC standards extend the polynomial division algorithm by specifying an initial shift register value, a final Exclusive-Or step and, most critically, a bit ordering . As a result, the code seen in practice deviates confusingly from "pure" division, [2] and the register may shift left or right.

  4. Fixed-income attribution - Wikipedia

    Once a curve has been fitted, the user can then define various measures of shift, twist and butterfly, and calculate their values from the calculated parameters. For instance, the amount of shift in a curve modeled by a polynomial function can be modeled as the difference between the polynomial parameters at successive dates. In practice, the ...

    The normal distribution is NOT assumed nor required in the calculation of control limits. Thus making the IndX/mR chart a very robust tool. Thus making the IndX/mR chart a very robust tool. This is demonstrated by Wheeler using real-world data [ 4 ] , [ 5 ] and for a number of highly non-normal probability distributions.

  6. Linear-feedback shift register - Wikipedia

    en.wikipedia.org/wiki/Linear-feedback_shift_register

    In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.

  7. Process capability index - Wikipedia

    In the long term, processes can shift or drift significantly (most control charts are only sensitive to changes of 1.5σ or greater in process output). If there was a 1.5 sigma shift 1.5σ off of target in the processes (see Six Sigma), it would then produce these relationships: [5]

  8. CUSUM - Wikipedia

    This differs from SPRT by always using zero function as the lower "holding barrier" rather than an actual lower "holding barrier". [1] Also, CUSUM does not require the use of the likelihood function. As a means of assessing CUSUM's performance, Page defined the average run length (A.R.L.) metric ; "the expected number of articles sampled before ...
