# Talk:Documentation/Calc Functions/STEYX

(1) General. The information at https://wiki.openoffice.org/wiki/Documentation/How_Tos/Calc:_STEYX_function may be helpful.
(2) Summary. Suggest the following replacement – “Fits a straight line to supplied data using linear regression and returns the standard error of actual y-values compared to y-values on the straight line found”.
(3) Arguments, DataY. Is a matrix different from an array in this context? Suggest change “the predicted values” to “real values representing the y-components of points in a data set”.
(4) Arguments, DataX. Is a matrix different from an array in this context? Suggest change “the values for which the corresponding y values are predicted” to “real values representing the x-components of points in a data set”.
(5) Arguments, 1st bullet. It would be worth clarifying what the text “Numbers can also be entered directly” refers to.
(6) Arguments, 2nd bullet. As with other functions where similar text occurs, I am not sure whether “a name/array/reference to” is necessary or not. Also, are we sure that logical values like TRUE and FALSE are ignored?
(7) Arguments, 3rd bullet. Change “has” to “contains” and “considers” to “includes”.
(8) Arguments, 4th bullet. I suspect that “length” should be changed to “dimensions” and “is” should be changed to “are”.
(9) Additional details. Please advise where this formula comes from – it is not the same as that in the ODF or that on the relevant Microsoft page.
(10) Examples, 1st example. Error in formula – semicolon after B1 should be a colon. Also change “reference to a range of cells” to “references to ranges of cells”.
(11) Examples, 2nd example. “array” should be plural.
