Considering that the specific of this method is \u201cthat it looks for components that are both statistically independent and Non-Gaussian, we try to apply ICA method on labour market data. Following the methodology presented by Hyv\u00e4rinen, Karhunen, Oja (2001) on the problem\u201d cashflow of several stores belonging to the same retail chain, trying to find fundamental factors common to all stores that affect the cash flow\u201d we apply on analysing the unemployment rates, seasonally adjusted, in monthly variation at EU27 level between January 2000-September 2011. The data source is EUROSTAT, indicator [une_rt_m]: \u201eUnemployment rate, monthly average, seasonally adjusted data, total (%), resulting 141 months\/cases. Orginal mixture data are pre-processing in the stage of Pre-whitened using Principal Component Analysis PCA, with NIPALS algorithm and for ICA the FastICA Algorithm from STATISTICA 8.0 Software.<br \/>\n<em><a href=\"..\/ARTICLES\/June_2013\/3.pdf\" target=\"_blank\" rel=\"noopener\">read more<\/a><br \/>\n<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cristina LINKARU National Institute for Science Research in The Field of Labour and Social Protection- INCSMPS, Romania, e-mail: cristina.lincaru@yahoo.de Vasilica CIUC\u0102 National Institute for Science Research in The Field of Labour and Social Protection- INCSMPS, Romania, e-mail: silviaciuca@incsmps.ro Speran\u0163a P\u00ceRCIOG National Institute for Science Research in The Field of Labour and Social Protection- INCSMPS, Romania,&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[181],"tags":[],"class_list":["post-2081","post","type-post","status-publish","format-standard","hentry","category-published"],"_links":{"self":[{"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/posts\/2081","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2081"}],"version-history":[{"count":3,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/posts\/2081\/revisions"}],"predecessor-version":[{"id":3736,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=\/wp\/v2\/posts\/2081\/revisions\/3736"}],"wp:attachment":[{"href":"https:\/\/rsijournal.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2081"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2081"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rsijournal.eu\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2081"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
