Origin

JMP was developed by SAS Institute Inc., Cary, NC. JMP is not a part of the SAS System, though portions of JMP were adapted from routines in the SAS System, particularly for linear algebra and probability calculations. Version 1 of JMP went into production in October 1989.

Introducing JMP

Using JMP statistical software, you can interact with your graphs and data to do the following:

Discover Using graphics, you can see patterns and relationships in your data, and find data that does

not fit identifiable patterns.

Interact Using JMP interactive features, you can follow up on clues and try different approaches. The

more approaches you try, the more you likely you are to discover trends in your data.

Understand Using graphics, you can see how the data and the model work together to produce the

statistics. Because JMP is a progressively disclosed system, you learn statistics methods in the right context.

Here are just a few of the things you can do with JMP:

• Interact with data tables and reports.

• Compute values using the Formula Editor.

• Design experiments.

• Use scripting features to automate frequently used processes.

• Open SAS data sets, run stored processes, and submit SAS code.

Prerequisites

Before you begin using JMP, note the following information:

• You can use many JMP features, such as data manipulation, graphs, and scripting features, without any statistical knowledge.

• A basic understanding of central statistical concepts, such as mean and variation, is recommended.

• Analytical features require statistical knowledge appropriate for the feature.

JMP Terminology

• You can enter, view, edit, and manipulate data using data tables. In a data table, each variable is a column, and each observation is a row.

• You can access a platform from the that you can use to analyze data and work with graphs.

• Platforms use these windows:

– Launch windows where you set up and run your analysis.

– Report windows showing the output of your analysis.

• Report windows normally contain the following items:

– A graph of some type (such as a scatterplot or a chart).

–Specific reports that you can show or hide using the disclosure button .

–Platform options that are located within red triangle menus .

Analyze and Graph menus. Platforms contain interactive windows

Use JMP Platforms

JMP uses many statistical methods that are organized and consolidated into the platforms within the

Analyze and Graph menus.

Work with Multiple Data Tables and Platforms

As mentioned earlier, platforms use interactive windows that help you analyze data and work with graphs. You can have any number of data tables open at the same time and any number of platforms open for each data table. If you have several data tables open, then the platform that you launch analyzes the current data table. The current data table is either the active data table window or the table corresponding to the current report window.

Chapter 1 Preliminaries 9

Use JMP Platforms

How JMP Platforms Are Designed

Before you use JMP’s statistical platforms, note the following design aspects of JMP:

• JMP implements general methods that are consistent with its key concepts. Although platforms produce a variety of results that handle many situations, all platforms are consistent in their treatment of data and statistical concepts.

• JMP methods are generic. They adapt themselves to the context at hand. The principal concept that drives analyses is modeling type. For details, see “Assign Mod e ling Type s , ” p. 9. For example, JMP automatically analyzes a variable with nominal values differently than it analyzes a variable with continuous values.

• JMP platforms give you almost everything that you need at once. If this is more information than you want, you can conceal the reports or graphs that you do not need. The advantage is that there is less need to search for statistical commands.

Process for Analyzing Data Using Platforms

To begin analyzing your data, proceed as follows:

1. With your data table open, assign or change modeling types, as needed. See “Assign Modeling Types,”

p. 9.

2. Choose an analysis and launch the corresponding platform. See “Choose an Analysis and Launching a

Platform,” p. 11.

3. Complete the launch window. See “Complete a Launch Window,” p. 11.

4. View the report window. See “View a Report Window,” p. 11.

Assign Modeling Types

Note: For more details about working with modeling types, see Using JMP.

The modeling type of a variable can be one of the following types, shown with its corresponding icon:

• Continuous

•Ordinal

• Nominal

When you import data into JMP, it predicts which modeling types to use. Character data is considered nominal, and numeric data is considered continuous. However, you might want to change the modeling type, depending on which type of analysis you are performing.

To change the modeling type, click on the modeling type icon next to the variable and make your selection.

10 Preliminaries Chapter 1

Use JMP Platforms

Figure 1.2 Changing Modeling Type

About Modeling Types

The modeling type tells JMP how to treat its values during analyses. Changing the modeling type lets you look at a variable in different ways in an analysis.

Ta bl e 1 .3 Descriptions of Modeling Types

Continuous

Columns can contain only numeric data types. Continuous values are treated as continuous measurement values. JMP uses the numeric values directly in computations.

Ordinal

Columns can contain either numeric or character data types. JMP analyses treat ordinal values as discrete categorical values that have an order. If the values are numbers, the order is the numeric magnitude. If the values are character, the order is the sorting sequence.

Nominal

Columns can contain either numeric or character data types. All values are treated in JMP analyses as if they are discrete values with no implicit order.
