mixedbiastest 1.0.3

• Correct term-specific covariance handling when several random-effects terms share a grouping factor. Earlier versions could use the first term’s variance for later terms.
• Correct permutations of multi-coefficient diagonal terms to preserve lme4’s group-major coefficient ordering. Handle diagonal covariance representations introduced in lme4 2.0, including the diag_special double-bar option.
• Transform diagnostics from automatically scaled fixed-effect designs back to the original coefficient scale, including intercepts and single predictors.
• Use lme4’s sparse fitted-model factors to compute the diagnostic without inverting the random-effects covariance or flooring zero variances.
• Enforce the documented exclusion of non-unit observation weights using the supported weights accessor, including fits with excluded observations.
• Validate permutation counts, contrasts, contrast names, and verbosity before calculation. List only retained fixed-effect coefficients for rank-deficient fits.
• Preserve full precision in returned bias estimates, permutation means and p-values; small nonzero permutation p-values are no longer rounded to zero. The two-sided test and +1 correction are unchanged.
• Run the regression suite during CRAN checks. Add independent dense-GLS and permutation-reference tests for supported inputs and recent lme4 changes. Gaussian unweighted fits with diagonal random-effects covariance remain the supported scope; correlated structures and GLMMs are not added.
