Normal Quantile Plot
CDF Plot
Provides the following options for plotting the quantiles of the
data in each group:
• Plot Actual by Quantile generates a quantile plot with the
response variable on the y-axis and quantiles on the x-axis.
The plot shows quantiles computed within each level of the
categorical X factor.
• Plot Quantile by Actual reverses the x- and y-axes.
• Line of Fit draws straight diagonal reference lines on the
plot for each level of the X variable. This option is available
only once you have created a plot (Actual by Quantile or
Quantile by Actual).
Plots the cumulative distribution function for all of the groups
in the Oneway report. See “CDF Plot” on page 161.
Densities Compares densities across groups. See “Densities” on page 161.
Matching Column
Save
Display Options
Specify a matching variable to perform a matching model
analysis. Use this option when the data in your Oneway analysis
comes from matched (paired) data, such as when observations
in different groups come from the same subject.
The plot now contains matching lines that connect the
matching points.
See “Matching Column” on page 161.
Saves the following quantities as new columns in the current
data table:
• Save Residuals saves values computed as the response
variable minus the mean of the response variable within
each level of the factor variable.
• Save Standardized saves standardized values of the
response variable computed within each level of the factor
variable. This is the centered response divided by the
standard deviation within each level.
• Save Normal Quantiles saves normal quantile values
computed within each level of the categorical factor
variable.
• Save Predicted saves the predicted mean of the response
variable for each level of the factor variable.
Adds or removes elements from the plot. See “Display Options”
on page 136.
