Options for Categorical Variables
Table 2.7 Description of Options for Categorical Variables (Continued)
Count Axis
Prob Axis
Density Axis
Show Percents
Show Counts
Adds an axis that shows the frequency of column values represented by the
histogram bars.
Adds an axis that shows the proportion of column values represented by
histogram bars.
Adds an axis that shows the length of the bars in the histogram.
The count and probability axes are based on the following calculations:
prob = (bar width)*density
count = (bar width)*density*(total count)
Labels the percent of column values represented by each histogram bar.
Labels the frequency of column values represented by each histogram bar.
Mosaic Plot
Order By
Test Probabilities
Confidence Interval
Displays a mosaic bar chart for each nominal or ordinal response variable. A
mosaic plot is a stacked bar chart where each segment is proportional to its
group’s frequency count.
Reorders the histogram, mosaic plot, and Frequencies report in ascending or
descending order, by count. To save the new order as a column property, use
the Save > Value Ordering option.
Displays a report that tests hypothesized probabilities. See “Examples of the
Test Probabilities Option” on page 62 for more details.
This menu contains confidence levels. Select a value that is listed, or select
Other to enter your own. JMP computes score confidence intervals.
The Save sub-menu contains the following options:
Level Numbers
Value Ordering
Script to log
Creates a new column in the data table called Level . The level
number of each observation corresponds to the histogram bar that contains
the observation.
(Use with the Order By option) Creates a new value ordering column
property in the data table, reflecting the new order.
Displays the script commands to generate the current report in the log
window. Select View > Log to see the log window.
Remove
Permanently removes the variable and all its reports from the Distribution
report.
