@saad-imran-dev, I think your implementation is missing repl.txt file

@saad-imran-dev, I think your implementation is missing repl.txt file

@ShabiShett07 I get this error whenever I try to add repl.txt and commit. Not able to resolve this error.

/stdlib/lib/node_modules/@stdlib/_tools/repl-txt/rules/match-signature/lib/main.js:61
                                if ( params[i].multiple !== sigParams[i-skip].multiple ) {

{{alias}}()
    Returns an accumulator function which incrementally computes a moving
    arithmetic mean and corrected sample standard deviation, ignoring
    `NaN` values.

    The `W` parameter defines the number of values over which to compute the
    moving arithmetic mean and corrected sample standard deviation.

    If provided a value, the accumulator function returns updated accumulated
    values. If not provided a value, the accumulator function returns
    the current moving accumulated values.

    As `W` values are needed to fill the window buffer, the first `W-1` returned
    accumulated values are calculated from smaller sample sizes. Until the
    window is full, each returned accumulated value is calculated from all
    provided values.

    Parameters
    ----------
    out: Array|TypedArray (optional)
        Output array.

    W: integer
        Window size.

    Returns
    -------
    acc: Function
        Accumulator function.

    Examples
    --------
    > var accumulator = {{alias}}( 3 );
    > var v = accumulator()
    null
    > v = accumulator( 2.0 )
    [ 2.0, 0.0 ]
    > v = accumulator( -5.0 )
    [ -1.5, ~4.95 ]
    > v = accumulator( NaN )
    [ -1.5, ~4.95 ]
    > v = accumulator( 3.0 )
    [ 0.0, ~4.36 ]
    > v = accumulator( 5.0 )
    [ 1.0, ~5.29 ]
    > v = accumulator( NaN )
    [ 1.0, ~5.29 ]
    > v = accumulator()
    [ 1.0, ~5.29 ]
