Count the number of zeroes in a column (JSL)

warnost

Hi,

I have been using the Distribution platform to manually analyze a data set, but since I will have to repeat I am now trying to create a JSL script to extract the measures that are most important. The data looks like this:

Model          Score

MODEL1     3.54485

MODEL2     2.36485

MODEL1     5.38456

MODEL2     2.14556

MODEL1     0

MODEL2     0.04856

I would like to extract the mean, std dev, etc. but also I would like to know how often the score is zero for each model. I have tried using summary, tabulate, and a few functions in JSL. I can accomplish everything but the "count zeroes" portion. I can get this number manually by creating the distribution and then doing histogram options >> show counts. Any ideas on how to do it in JSL? Code so far:

dt = Open("C:\Desktop\Results.jmp);

dt << Summary(

  Group( :Model ),

  Median( :score ),

  Mean( :score ),

  Std Dev( :score ),

  Range( :score ),

  );

ms

Here is a sligtly simplified version that should give the same result.

dt = Open( "C:\Desktop\results1" || filename || ".jmp" );

dt2 = dt << Summary( Group( :Model ), Median( :score ), Mean( :score ), Range( :score ) );

dt2 << Delete Rows( 2 ) << New Column( "Num Zeroes",

  Numeric,

  Continuous,

  Format( best ),

  <<set each value( N Rows( dt << get rows where( :score == 0 & :Model == "Model1" ) ) )

);
