ordvar calculates measures of ordinal consensus and dispersion. These include lsq and 1-lsq, which are 0/1 normed ordinal consensus and dispersion statistics described in Blair and Lacy (2000). The latter statistic is essentially identical to the IOV measure of Berry and Mielke (1992). The non-normed version of the dispersion statistic, termed d-squared by Lacy (2006), is also calculated, as are delta-method standard errors for these statistics. These measures do not rely on assumptions about intercategory distances or distributional form.
