NEWS file for the deming package

Changes in version 1.4-1

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

Changes in version 1.4

• 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.

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

• 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

• 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

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

• 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.

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

Changes in version 1.1

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