  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

    Use of a user-defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.

  4. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    Algorithms for calculating variance play a major role in computational statistics.A key difficulty in the design of good algorithms for this problem is that formulas for the variance may involve sums of squares, which can lead to numerical instability as well as to arithmetic overflow when dealing with large values.

  5. Cyclomatic complexity - Wikipedia

    en.wikipedia.org/wiki/Cyclomatic_complexity

    "linearly independent" corresponds to homology, and backtracking is not double-counted; "paths" corresponds to first homology (a path is a one-dimensional object); and "relative" means the path must begin and end at an entry (or exit) point. This cyclomatic complexity can be calculated.

  6. Critical path method - Wikipedia

    en.wikipedia.org/wiki/Critical_path_method

    The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. [1] A critical path is determined by identifying the longest stretch of dependent activities and measuring the time [2] required to complete them from start to finish.

  7. Path coefficient - Wikipedia

    en.wikipedia.org/wiki/Path_coefficient

    Path coefficients are standardized versions of linear regression weights which can be used in examining the possible causal linkage between statistical variables in the structural equation modeling approach. The standardization involves multiplying the ordinary regression coefficient by the standard deviations of the corresponding explanatory ...

  8. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics , a trajectory is defined by Hamiltonian mechanics via canonical coordinates ; hence, a complete trajectory is defined by position and momentum , simultaneously.

  9. Eightfold path (policy analysis) - Wikipedia

    en.wikipedia.org/wiki/Eightfold_Path_(policy...

    The eightfold path is a method of policy analysis assembled by Eugene Bardach, a professor at the Goldman School of Public Policy at the University of California, Berkeley. [1] It is outlined in his book A Practical Guide for Policy Analysis: The Eightfold Path to More Effective Problem Solving , which is now in its seventh edition. [ 2 ]
