dst v1.4.1 As of 2020-02-23 - added utility function bcaPrint for printing of the subsets of non-zero mass of a belief function. - added examples vignettes: Zadeh's example, Captain's problem - function dsrwon added a check on values names to ensure that the two bca's combined are defined on the same space. - function extmin added checks on names of variables, as well as their number and their position in a product space ============================ dst 1.4.0 version 1.4.0 published on CRAN 2019-08-20 - Correction to fn extmin: Added a test for variable names missing. - Correction to productSpace function. Transpose of array removed at the end of the function. ================ dst v 1.3.0 (on CRAN 2018-12-05) - added utility functions 'matrixToMarray' and 'marrayToMatrix' to execute the product space conversion of multidimensional data represented by a matrix, and vice-versa. - debugging of function 'extmin' (extension of data to a larger product space). - debugging of function 'elim' (reduction of a product space by elimination of one variable). ================ dst v1.2.0.9001 2018-07-07. - Correction to fn dsrwon: added the parameter relnb in the call of the function, to allow for specification the result with a new relation number. ================ dst v1.2.0.9000 2018-05-01. - Correction to fn tabresul: added a check for the case of the empty set present with m_empty = 0 ================ dst v1.1.0.9000 2018-05-01. - Correction to fn belplau: added a check for the case of the empty set present with m_empty = 0 - Re-writed the referencing of source code taken on Rpubs ================ dst v1.0.0 (Release date on CRAN: 2018-04-25) Changes from version 0.3: - Added a vignette: The Monty hall Game, an introduction to belief functions. - functions (new and updated): -- addTobca: New function. Adds some elements of 0 mass to an existing mass function. -- bca: New version. Sets a class named "bcaspec". Parameters added to work with definitions on product spaces (relations). -- bcaRel: New function to define a belief function on a product space. -- belplau: Calculation of measures of belief, plausibility and ratio of plausibility. -- decode: utility function -- dotprod: utility function -- double: utility function -- shape: utility function -- encode: New utility function. Convert a value to its representation in another chosen base. -- reduction: utility function to obtain the summary of a vector for any operator -- dsrwon: Combination of two mass functions -- elim: This is a new function. This function works on a relation defined on a product of two variables or more. Having fixed a variable to eliminate from the relation, the reduced product space is determined and the corresponding reduced bca is computed.This operation is also called "marginalization". -- extmin: Extension of a relation to a greater product space -- inters: Intersection of two tables of propositions -- nameRows: New function: Using the column names of a matrix to construct names for the rows -- nzdsr: Normalization of results from Dempster's rule of combination. -- productSpace: New function. Product space representation of a relation -- plautrans:Plausibility transformation of the singletons of a frame -- tabresul: Prepare a table of results. - Removal of obsolete functions: butLast, combmasses, dempster, initsing, rplau, transfo ================ dst v0.3: Initial release of package on CRAN (2015-01-13) ================
