如果缺少異常值 jsl 中沒有異常值，如何忽略？

我有一個在大型數據庫上運行的探索異常值 jsl。 有時explore outlier找不到任何異常值（因為數據分佈相當緊密），jsl報錯。 如何在以下腳本中添加 ignore 或 try 語句以跳過探索異常值代碼？

dt1 = Current Data Table();
eo = dt1 << Explore Outliers(
 Y( :var1 ),
 K Sigma( 2 ),
 Robust Fit Outliers,
 Where(
  :x == 1
 ),
 Invisible
);
eoRep = Report(eo);
table = eoRep[TableBox(1)];
colList = eoRep[StringColBox(1)];
// Loop over these columns . . .
nCols = NItems(colList << get);
for(c=1, c<=nCols, c++,
 // Select this column (described by a row)
 CMD = Expr( table << setSelectedRows({colTBD}) );
 SubstituteInto(CMD, Expr(colTBD), Eval(c));
 CMD;
 // Update dt2 for this column: Cells that were considered outliers are coloured red
 eo << ColorCells(1);
 eo << ChangeToMissing(1);
 );

數據表腳本視窗回复：如果缺少異常值 jsl 中沒有異常值，如何忽略？

我相信您可以通過簡單地檢查是否已找到零異常值來繞過處理

For( c = 1, c <= nCols, c++,
 If( (eoRep[Number Col Box( 3 )] << get)[c] != 0, 
 // Select this column (described by a row)
  CMD = Expr(
   table << setSelectedRows( {colTBD} )
  );
  Substitute Into( CMD, Expr( colTBD ), Eval( c ) );
  CMD;
 // Update dt2 for this column: Cells that were considered outliers are coloured red
  eo << ColorCells( 1 );
  eo << ChangeToMissing( 1 );
 )
);
