------- Additional comments from [EMAIL PROTECTED] Tue Jan 8 16:13:01 +0000 2008 ------- Hello, @hugovazquez : For me it's must have feature, as well for engineering. But saying that would never help programmers. At least you should vote for this issue. I think this issue should have more than 9 votes. To help going a little forward: this feature requires to modify dialog box of Regression Curve and Statistics, as for "moving average" regression type (issue 66819). These two issues may be resolved simultaneously. The minimum to do (to be compatible with MS-Excel), is to have the order of the polynom (default should be 2) as explained in issue 77930. To go farther, minimum (default 0) and maximum orders should be given, as in the macro of Laurent Godard (see attachment). Exponential terms are useless for me, but may be Laurent Godard has examples where it is necessary. All these values require to be added in the dialog boxes. One problem which may occur during calculation of coefficients, is a non inversible matrix. I don't know which conditions are necessary to avoid this problem. Another problem in case of negative orders, will be with null values of x. Hope it could help resolving this feature... for OOo 3.0?
