A general method to prove implications involving the conditional independences is presented. The method relies on computations of a Groebner basis. Examples of the implications are discussed.</abstract> <abstract language="cze" primary="0">Inference podmíněné nezávislosti v gaussovských vektorech je studována algebraickými metodami. Je prezentována obecná metoda důkazu implikací mezi podmíněnými nezávislostmi. Tato metoda spočívá ve výpočtu jisté Groebnerovi báze. Jsou uvedené příklady nových implikací.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0213217</ARLID> <name>International Workshop WCII 2002</name> <place>Hagen</place> <country>DE</country> <dates>13.05.2002-15.05.2002</dates>  </action>     <RIV>BA</RIV> <reportyear>2006</reportyear>   <department>MTR</department>    <permalink>http://hdl.handle.net/11104/0131451</permalink>    <ID_orig>UTIA-B 20050099</ID_orig>    <arlyear>2005</arlyear>       <unknown tag="mrcbU63"> Conditionals, Information, and Inference, International Workshop.
