Outliers more than 3 standard deviations in JMP

NeF

Hi, 

Is there any way to detect outliers more than 3 stansard deviations in JMP?  

I should say that I am familiar with the "explore outliers option as well as "Levey Jennings" Control chart. but, is there other way to detect outliers more than 3SDs? 

thanks, 

Ne

This can be solved by creating a new formula column with the formula:

 

If( :Data > Col Mean( :Data ) + Col Std Dev( :Data ) * 3,
    1,
    0
)

 

The data column is your source column.

 

In case you want the vaules > 3SDs, the formula is:

 

If( :Data > Col Mean( :Data ) + Col Std Dev( :Data ) * 3,
    :Data,
    "."
)
