Need to populate no of unique enteryI need to populate no of unique entries in a new column if Flagged="Yes". When I use Col N Unique formula I get Different count if Flagged="No".

Basic Data Analysis and ModelingRe: Need to populate no of unique enteryYou are using Flagged == "Yes" as grouping "column" so it will calculate separate unique values for Yes and No.
Re: Need to populate no of unique enteryAny suggestion for how to populate Yes calculation in entire column?
Re: Need to populate no of unique enteryI don't have JMP 19, so no Col N Unique(), but I think this gets you what you want. As Constant() makes the evaluation much faster.
As Constant( Length( Associative Array( :SN[Where( :Flagged == "Yes" )] ) << Get Keys ) )
Re: Need to populate no of unique enteryCurrent Data Table() << NEW COLUMN("A", Numeric, Formula(
Col Sum(If(:Column 2 == "y" & Row() == Col Min(Row(), :Column 1), 1, 0))
));
I don't use JMP19 so I'm not that familiar with Col N Unique but maybe something like this
Current Data Table() << NEW COLUMN("A", Numeric, Formula(
Col Max(If(:Column 2 == "y", Col N Unique(:Column 1, :Column 2), .))
));
Column 1 is SN and Column 2 is flagged
Re: Need to populate no of unique enteryThe Col N unique() function is so helpful!
It makes many analyses much easier.
I hope,

will work in JMP 19.x.
Looks straight forward- but at the moment this doesn't work
- unfortunately, Col N Unique() behaved different to the other col ... aggregations:

[from Tiny Traps in Jmp and JSL ].
Re: Need to populate no of unique enteryOther details you should be aware of:
Col score & Col N unique
Re: Need to populate no of unique enterytxnelson edit: This is not a solution. See @hogi answer below.
Here is how I would do it:
Current Data Table() << New Column( "A",
Numeric,
Formula(
As Constant(
theCount = N Rows(
Current Data Table() <<
get rows where( :column 2 == "y" )
)
);
theCount;
)
);
Re: Need to populate no of unique enteryJMP 18:
New Column( "unique",
Formula(
As Constant(
Length(
Associative Array( :SN[Where( :Flagged == "Yes" )] ) << Get Keys
)
)
)
)
JMP19:
dt << New Column( "unique",
Formula(
Col Max(
If( :Column 2 == "y",
Col N Unique( :Column 1, :Column 2 ),
.
)
)
)
);
JMP 19.x:
dt << new column("unique",
Formula( Col N Unique(If(:Flagged == "y",:SN, .) )
));
JMP20?
dt << new column("unique",
Formula( Col N Unique(:SN, Where(:Flagged) )
));
The last one is my favorite - it will facilitate certain types of data analysis a lot!
please vote: Col Median (and others): add "Where" option
otherwise we have to wait for v25 ...
