JMP 14.0

This section describes changes in scripting between 13.2 and 14.0.

The “Exchangeable” covariance structure has been renamed “Compound Symmetry”. In the report for a pure variance component analysis, the “Covariance Parameter” column is now named “Variance Components”. You must update scripts that were previously saved from Mixed Models.

Journals

Journals that are created in JMP 14 or later might contain compressed matrix data for large matrices. If you have JSL scripts that open journals and extract data from them, you might need to use the Get Journal message (which does not compress the matrices) rather than saving the journal to disk with the Save Journal message.

Tab Boxes

In JMP 13, if you pass Tab Page Box() to Tab Box<<Add, <<Append, <<Insert, or <<Replace, the result is Tab Page Box() contained with a Tab Page Box(), because these functions wrap the provided content.

In JMP 14, we avoid the double nesting in these instances. Here are examples of the syntax:

Tab Box << Add( <index>, Tab Page Box(...) );

Tab Box << Insert( <index>, Tab Page Box(...) );

Tab Box << Append( <index>, Tab Page Box(...) );

Tab Box << Replace( <index>, Tab Page Box(...) );

Boolean Constants and Null

If the Allow Boolean and Null Constraints preference has been turned on in a script, you cannot use true, false, and null as variable names.

Remove() and Remove From()

A value of 0 for the number of items to remove now removes no items rather than defaulting to one item.

Normal Mixtures Message in K Means Cluster Script

The Normal Mixtures message no longer works in K Means Cluster scripts now that K Means has been separated from Normal Mixtures.

The preferred syntax for the script follows:

Normal Mixtures(

	Y( :Sepal length, :Sepal width, :Petal length, :Petal width ),

	{Mixtures Tolerance( 0.00000001 ), Mixtures MaxIter( 300 ),

	Mixtures N Starts( 30 ), Outlier Cluster( 0 ), Diagonal Variance( 0 ),

	Number of Clusters( 3 ), Go}

);

Text Explorer

The Weighting() and Centering and Scaling() arguments for an SVD analysis in Text Explorer are now required. To avoid having a Specifications window appear, update Text Explorer scripts to include Weighting() and Centering and Scaling() arguments in the Latent Semantic Analysis() argument. The Maximum Number of Terms() and Minimum Term Frequency() arguments are also required to avoid the Specifications window.

Summarizing with Row States

When you summarize data that contain row states, the summary statistics are not calculated. An error appears in the log instead.

Least Squares Solve()

The order of the first two arguments to Least Squares Solve() has switched; the response vector is now the first argument, and the design matrix is the second argument. Also, Least Squares Solve() now includes an intercept term by default. Use the optional nointercept message to specify a model without an intercept.

Maximum() and Minimum()

Maximum() and Minimum() no longer work on a list of strings. As an additional note, Maximum() and Minimum() for strings never actually worked. It returned the last one in the list.

Transform Columns in Custom Display Boxes

To add a transform column to a custom display box, use Filter Col Selector() instead of Col List Box(). You also don’t need to use Column Reference.

Tree Nodes

A tree box Set Node Select Script message might need special attention if the JSL will run on both Windows and Macintosh. In a nested tree with a child selected under a collapsed parent node, the script will not be called on Windows and will be called twice on Macintosh.
