If a value is missing, it is replaced by one of the functions "minimum", "maximum", "average", and "none", which is applied to the non missing attribute values of the example set. "none" means, that the value is not replaced. The function can be selected using the parameter list <code>columns</code>. If an attribute's name appears in this list as a key, the value is used as the function name. If the attribute's name is not in the list, the function specified by the <code>default</code> parameter is used. For nominal attributes the mode is used for the average, i.e. the nominal value which occurs most often in the data. For nominal attributes and replacement type zero the first nominal value defined for this attribute is used. The replenishment "value" indicates that the user defined parameter should be used for the replacement.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: MissingValueReplenishment.java,v 1.7 2006/03/21 15:35:52 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo Mierswa, Simon Fischer</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR></TABLE> <A NAME="fields_inherited_from_class_com.rapidminer.operator.preprocessing.filter.ValueReplenishment"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Fields inherited from class com.rapidminer.operator.preprocessing.filter.<A HREF="../../../../../com/rapidminer/operator/preprocessing/filter/ValueReplenishment.html" title="class in com.rapidminer.operator.preprocessing.filter">ValueReplenishment</A></B></TH>⌨️ 快捷键说明
