Save Options for Continuous Variables

Use the Save menu options to save information about continuous variables. Each Save option generates a new column in the current data table. The new column is named by appending the variable name (denoted <colname> in the following definitions) to the Save command name. See Table 2.1.

Select the Save options repeatedly to save the same information multiple times under different circumstances, such as before and after combining histogram bars. If you use a Save option multiple times, the column name is numbered (name1, name2, and so on) to ensure unique column names.

Table 2.1 Descriptions of Save Options
Option	Column Added to Data Table	Description
Level Numbers	Level <colname>	The level number of each observation corresponds to the histogram bar that contains the observation. The histogram bars are numbered from low to high, beginning with 1. Note: To maintain source information, value labels are added to the new column, but they are turned off by default.
Level Midpoints	Midpoint <colname>	The midpoint value for each observation is computed by adding half the level width to the lower level bound. Note: To maintain source information, value labels are added to the new column, but they are turned off by default.
Ranks	Ranked <colname>	Provides a ranking for each of the corresponding column’s values starting at 1. Duplicate response values are assigned consecutive ranks in order of their occurrence in the data table.
Ranks averaged	RankAvgd <colname>	If a value is unique, then the averaged rank is the same as the rank. If a value occurs k times, the average rank is computed as the sum of the value’s ranks divided by k.
Prob Scores	Prob <colname>	For N nonmissing scores, the probability score of a value is computed as the averaged rank of that value divided by N + 1. This column is similar to the empirical cumulative distribution function.
Normal Quantiles	N-Quantile <colname>	Saves the Normal quantiles. See Normal Quantile Plot.
Standardized	Std <colname>	Saves standardized values. See Saving Standardized Data.
Centered	Centered <colname>	Saves values for centering on zero.
Robust Standardized	Robust Std <colname>	Saves a column that contains the response value centered around the robust mean and standardized using the robust standard deviation.
Robust Centered	Robust Centered <colname>	Saves a column that contains the response value centered around the robust mean.
Spec Limits	(none)	Stores the specification limits applied in a capability analysis as a column property of the corresponding column in the current data table. Automatically retrieves and displays the specification limits when you repeat the capability analysis.
Script to Log	(none)	Prints the script to the log window. Run the script to recreate the analysis.
