Changes in version 1.4-1 (2024-06-26)                  

    o   Fix a few errors in the documentation and help files.

                  Changes in version 1.4 (2018-11-13)                   

    o   Major user visible change: Tor Wentzel-Larsen gently pointed
	out that I misspelled Theil's name as "Thiel" more than 1/2 the
	time (but not always), including the actual name of the
	function.  This has been repaired.

    o   Update the documentation to acknowledge "total least squares",
	a completely separate, and larger, literature that parallels
	and extends Deming regression.

    o   Add a further data check.  One user used the deming 'cv' option
	along with data that was negative (which implies a negative
	variance), and the routine did not fail nicely.

                  Changes in version 1.3 (2018-10-08)                   

    o   Version 1.2 had left a browser() call behind, which was
	encountered when doing regression through the origin.  Pointed
	out by Daniela Herold.  Add a no intercept regression to the
	test suite.

                  Changes in version 1.2 (2018-06-19)                   

    o   Add importFrom directive for calls to functions from "stats",
	per 2015/7/1 change in CRAN checks

    o   Fix bug for the case of no intercept and the presence of stdx
	and stdy: an "as.matrix" was needed for the lm.wfit call.

    o   Change the bootstrap to use residuals orthagonal to the fitted
	line.  This makes the functions rotationally invariant.

                         Changes in version 1.1                         

    o   Add the id option to the deming function, to allow for group
	jackknife estimates of variance.
