For instances where the time-shifted value is unknown either the instance may be dropped, or missing values used.<p> Valid filter-specific options are:<p> -R index1,index2-index4,...<br> Specify list of columns to calculate new values for. First and last are valid indexes. (default none)<p> -V <br> Invert matching sense (i.e. calculate for all non-specified columns)<p> -I num <br> The number of instances forward to take value differences between. A negative number indicates taking values from a past instance. (default -1) <p> -M <br> For instances at the beginning or end of the dataset where the delta values are not known, use missing values (default is to remove those instances). <p><P><DL><DT><B>See Also: </B><DD><A HREF="../../serialized-form.html#weka.filters.TimeSeriesDeltaFilter">Serialized Form</A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="fields_inherited_from_class_weka.filters.AbstractTimeSeriesFilter"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class weka.filters.<A HREF="../../weka/filters/AbstractTimeSeriesFilter.html">AbstractTimeSeriesFilter</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../weka/filters/AbstractTimeSeriesFilter.html#m_FillWithMissing">m_FillWithMissing</A>, <A HREF="../../weka/filters/AbstractTimeSeriesFilter.html#m_History">m_History</A>, <A HREF="../../weka/filters/AbstractTimeSeriesFilter.html#m_InstanceRange">m_InstanceRange</A>, <A HREF="../../weka/filters/AbstractTimeSeriesFilter.html#m_SelectedCols">m_SelectedCols</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_weka.filters.Filter"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class weka.filters.<A HREF="../../weka/filters/Filter.html">Filter</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../weka/filters/Filter.html#m_NewBatch">m_NewBatch</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../weka/filters/TimeSeriesDeltaFilter.html#TimeSeriesDeltaFilter()">TimeSeriesDeltaFilter</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../weka/filters/TimeSeriesDeltaFilter.html#main(java.lang.String[])">main</A></B>(java.lang.String[] argv)</CODE><BR> Main method for testing this class.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../weka/core/Instance.html">Instance</A></CODE></FONT></TD>⌨️ 快捷键说明
