I uploaded today to CRAN an updated version of tsintermittent<\/a>. Yesterday I found a bug in the optimisation of the Croston’s, SBA and TSB methods and this update fixes that. Here is the changelog for this update:<\/p>\n

Version 1.3 (04 August 2014)\r\n  * Corrected major optimisation bug - issue with opt.on in all crost, \r\n    tsb and sexsm functions.\r\n  * Corrected bug in imapa function when maximumAL was very high.\r\n  * Corrected bugs in the legend of imapa function plots.\r\n  * Added option to optimise only initial values without parameters in \r\n    crost, tsb and sexsm functions.\r\n  * Added init.opt option for imapa in the same way as it is for crost \r\n    and tsb functions. This does not affect SES optimisation.\r\n  * Added option to use pre-fitted imapa models.\r\n<\/pre>\nIf you had experienced some strange behaviour with optimising the various methods, especially SBA, this update fixes this. I strongly suggest you update the intermittent demand package to version 1.3 as soon as possible!<\/p>\nRelated Posts<\/H3>Intermittent demand & THieF – EJOR Editors\u2019 Choice Articles<\/a><\/li>\n
