Input Table(s) or Column(s).

Type: Table, Column, List, Required, Single

Unbiased Boolean

Use Bessel's correction for an unbiased estimation of the variance.

Select Columns

Select By Selection

Method of selection. Range lets you specify the start and stop rows to include. Index specifies the selected rows via a numeric array, i.e. to get the first and third row, input [0,2]. Bit Mask selects the rows using True/False notation, i.e. if you want the first and third row in a Table, input [1,0,1,0,0].

Values: Range, Index, Bit Mask, Names

Column Names Text

Comma separated string with column names.

Start Index Text

If Range is selected, this specifies the first selected column.

Stop Index Text

If Range is selected, this specifies the last selected column.

Indices Integers

If Index is selected, input selected column indeces here as a numeric array of integers.

Bit Mask Bits

If Bit Mask is selected, input the selected columns via a boolean array.
