How to find the mode of multiple columns and partial rows?

[#1]

For example, add new columns with "Big Class. JMP ", and find the mode of the data in the same row of the "height"、"weight" columns and the five rows above.

Thanks!

mode(Range(:weight[Index(Row()-5,Row())], :height[Index(Row()-5,Row())]))

• I can't get the right answer by using this formula.

Thanks!

Here is the formula that I came up with

If( Row() > 6,
	Mode( Matrix( :height[Index( Row() - 5, Row() )] ) || Matrix( :weight[Index( Row() - 5, Row() )] ) ),
	Mode( Matrix( :height[Index( 1, Row() )] ) || Matrix( :weight[Index( 1, Row() )] ) )
)

Note: The Range() function returns the minimum and maximum values found in the list or matrix

Note: JMP returns the minimum mode value if there is more than one mode 

mode([77,55,33,77,55])

returns

55

while

mode([55,34,67,88,65])

returns

34

Thank Jim!

The JMP mode formula seems rather lax.

In Excel, no mode is returned as "#N/A", and JMP is returned as "minimum".

The minimum is a correct mode.  There just happens to be more than one mode.

Whether this can be verified

It is a simple matter to determine if more than one value was found that determined what the mode is.  If you want to set the resulting mode to a missing value when the mode comes from a single value, you can use the below logic

Names Default To Here( 1 );
mat = [1, 2, 3, 4, 5, 1];
xmode = Mode( mat );
If( N Rows( Loc( mat, xmode ) ) == 1,
	x = .
);
Show( xmode );
