  2. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    ECMs are a theoretically-driven approach useful for estimating both short-term and long-term effects of one time series on another. The term error-correction relates to the fact that last-period's deviation from a long-run equilibrium, the error, influences its short-run dynamics. Thus ECMs directly estimate the speed at which a dependent ...

  3. Predicted Aligned Error - Wikipedia

    en.wikipedia.org/wiki/Predicted_Aligned_Error

    Interpretation of PAE values allows scientists to understand the level of confidence in the predicted structure of a protein: Lower PAE values between residue pairs from different domains indicate that the model predicts well-defined relative positions and orientations for those domains.

  4. Spreadsheet - Wikipedia

    A cell on a different sheet of the same spreadsheet is usually addressed as: =SHEET2!A1 (that is; the first cell in sheet 2 of the same spreadsheet). Some spreadsheet implementations in Excel allow cell references to another spreadsheet (not the currently open and active file) on the same computer or a local network.

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

  6. Nelder–Mead method - Wikipedia

    en.wikipedia.org/wiki/Nelder–Mead_method

    Simulation of such complicated structures is often extremely computationally expensive to run, possibly taking upwards of hours per execution. The Nelder–Mead method requires, in the original variant, no more than two evaluations per iteration, except for the shrink operation described later, which is attractive compared to some other direct ...

  8. Contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Contact_mechanics

    It is recognized that the self affine structure of surfaces is the origin of the linear scaling of true contact area with applied pressure. [ 30 ] [ 31 ] Assuming a model of shearing welded contacts in tribological interactions, this ubiquitously observed linearity between contact area and pressure can also be considered the origin of the ...

  9. Iterative method - Wikipedia

    en.wikipedia.org/wiki/Iterative_method

    Attractive fixed points [ edit ] If an equation can be put into the form f ( x ) = x , and a solution x is an attractive fixed point of the function f , then one may begin with a point x 1 in the basin of attraction of x , and let x n +1 = f ( x n ) for n ≥ 1, and the sequence { x n } n ≥ 1 will converge to the solution x .
