## Does JMP have a SumIf equivalent in Column Formula Editor?

I will explain what I am trying to achieve with an example

ID Value Sum
1 5 13
1 6 13
2 9 9
3 1 1
1 2 13

I have a column with a bunch of IDs, they can repeat. Then a have a second column with different values for those IDs.

On the 3rd column, I am trying to have a formula to sum all the Values from all the rows that have the same ID as the current row.

For Row 1 we have, ID = 1, so 5+6+2= 13

Any ideas on how to do that?

## Re: SumIf equivalent in Column Formula

Using the ColSum() function with a second argument to specify a By variable should work. The script below recreates your table, using a formula for the third column:

New Table( "Data",

New Column( "ID",

Numeric,

"Continuous",

Set Values( [1, 1, 2, 3, 1] )

),

New Column( "Value",

Numeric,

"Continuous",

Set Values( [5, 6, 9, 1, 2] )

),

New Column( "SumIf",

Numeric,

"Continuous",

Formula( Col Sum( :Value, :ID ) )

)

)

Hope that helps,
