Figure 3.34 A Missing Data Pattern Table
Figure 3.34 shows the following patterns:
• Row 1 shows that there are two instances where all rows in Trial 1, Trial 2, Trial 3, and Trial 4 have
no missing values.
• Row 2 shows that there are two rows in the source table whose one missing value is in the Trial 4
column.
• Row 3 shows that there are two rows in the source table whose missing values are in the Trial 3 and
Trial 4 columns.
• Row 4 shows that there is one row in the source table whose three missing values are in the Trial 2,
Trial 3, and Trial 4 columns.
In the Missing Data Pattern table, JMP automatically assigns the Count column the analysis role of
frequency. Now if you use the Missing Data Pattern data table to run an analysis, JMP automatically
uses Count as a frequency so you do not have to specify its role each time. See “Giving Columns a
Preselected Analysis Role,” p. 138, for details.
Finding and Replacing Cell Values
Selecting Edit > Search gives you many search options, as shown in Figure 3.35. The following rules
apply to searching for values:
• To find values in hidden columns or locked tables, unhide the column or unlock the table.
• Values found in locked columns cannot be modified.
