The OUTLIMITS= data set saves decision limits and decision limit parameters. The following variables can be saved:
Table 4.11: OUTLIMITS= Data Set
Variable 
Description 


significance level () 

groupvariable specified in the PCHART statement 

optional identifier for the decision limits specified with the OUTINDEX= option 

lower decision limit for proportions 

number of groups 

nominal sample size associated with the decision limits 

average proportion of nonconforming items () 

type (standard or estimate) of 

upper decision limit for proportions 

response specified in the PCHART statement 
Notes:
If the decision limits vary with group sample size, the special missing value V is assigned to the variables _LIMITN_
, _LDLP_
, and _UDLP_
.
A group must have at least one nonmissing value (), and there must be at least one group with .
Optional BY variables are saved in the OUTLIMITS= data set.
The OUTLIMITS= data set contains one observation for each response specified in the PCHART statement. For an example, see Saving Decision Limits.
The OUTSUMMARY= data set saves group summary statistics. The following variables are saved:
the groupvariable
a group proportion variable named by response suffixed with P
a group sample size variable named by response suffixed with N
Given a response name that contains 32 characters, the procedure first shortens the name to its first 16 characters and its last 15 characters, and then it adds the suffix.
Group summary variables are created for each response specified in the PCHART statement. For example, consider the following statements:
proc anom data=Input; pchart (Rework Rejected)*Batch / outsummary=Summary groupn =30; run;
The data set Summary
contains variables named Batch
, ReworkP
, ReworkN
, RejetedP
, and RejetedN
.
Additionally, the following variables, if specified, are included:
BY variables
blockvariables
symbolvariable
ID variables
_PHASE_
(if the OUTPHASE= option is specified)
For an example of an OUTSUMMARY= data set, see Saving Group Proportions.
Note that an OUTSUMMARY= data set created with the PCHART statement can be reused as a SUMMARY= data set.
The OUTTABLE= data set saves group summary statistics, decision limits, and related information. The variables shown in the following table are saved:
Variable 
Description 


significance level () 

decision limit exceeded on p chart 
group 
values of the group variable 

lower decision limit for proportions 

nominal sample size associated with the decision limits 

group proportion 

group sample size 

upper decision limit for proportions 

response specified in the PCHART statement 
In addition, the following variables, if specified, are included:
BY variables
blockvariables
symbolvariable
ID variables
_PHASE_
(if the READPHASES= option is specified)
Note: The variable _EXLIM_
is a character variable of length 8. The variable _PHASE_
is a character variable of length 48. The variable _VAR_
is a character variable whose length is no greater than 32. All other variables are numeric.
For an example, see Saving Decision Limits.
