    This function calculates the statistics for a line.




    The equation for the line is y=mx+b or y=m1x1+m2x2+...+b.

    This function has these arguments:

    Argument Description
    y Set of y values that are known in the relationship y=mx+b
    x (Optional) X is an optional set of x values that may be known in the relationship y=mx+b
    constant Logical value that specifies whether to force the constant b to equal 0. If true or omitted then b is calculated normally; if false then b is equal to 0 and the m values are adjusted so that y=mx.
    stats Logical value that specifies whether to return additional regression statistics. If true, then the additional regression statistics are returned if false or omitted then only the m-coefficients and b are returned.

    If x is omitted then x defaults to the array {1,2,3...}, that has the same dimensions as y.


    Use the INDEX function to get individual elements from the returned array.
