• Documentation updates.
• Remove unused setAs definitions.
• expectation(), variance() and covariance() return named vectors or matrices. Names for objects returned by statistic() have been partially improved.
• All observations with NAs are removed now.
• Some internal improvements (removed unused code, avoid duplicated code chunks etc.).
• More checks on NAs, blocks and multiple ordinal variables (one univariate problems are currently allowed to have ordinal variables).
