* Fix Unintential Deprecated Calls in Tests - STATISTICAL I think it's best to install these before PR #3166. There are no changes to source code, only to doc-blocks and to test members which continue to inadvertently use calls to deprecated functions. * Missed One Deprecation Fix it now. * Run Tests in Spreadsheet Context This is quite a bit more difficult for Statistical than for the other Calculation categories. This is partly because of the use of multi-dimensional matrices, and also because some arguments are interpreted differently when they come from a cell rather than entered directly in a formula. This push leaves 18 out of 89 test members unchanged, except that they are marked with a TODO to show that the work isn't finished. I will not revisit them as part of this PR, but probably will take a look in a subsequent ticket.
