I am trying to supress outliers in a continuous variable. In SPSS I used to just declaire a range and recode them as missing values. I know this should be obvious, but I need some help

thanks

Re: supress outliers

@emeritus ,

You can use the hide and select approach. Here try this:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" ); // Open a sample data table

// Defining the range which you feel are outliers
dt << Select Where (:height < 62);

// Hiding and Excluding them from your analysis (they will remain in the data table, but are not included in your

//analysis
dt << Hide and Exclude;

// Clear your selection
dt << Clear Select;

// Perform a simple bivariate analysis - notice that the values for height < 62 no longer show up in your plot
dt << Bivariate( Y( :weight ), X( :height ), Fit Line );

Best

Re: supress outliers

I would use the Column Property, "Range Check". It allows you to remove outliers on a column by column basis.

Re: supress outliers

I actually looked at that but got scared off because I did not totally understand it. I will give it a shot.

Thanks
