OCASNZ4M

This function takes the data frame=plan created by the AAZ14Multiple function and and a vector of proportion defectives=pd. It calculates OC and ASN values and creates a data frame.

Functions are included for recalling AQL (Acceptable Quality Level or Acceptance Quality Level)
Based single, double, and multiple attribute sampling plans from the Military Standard (MIL-STD-105E) - American
National Standards Institute/American Society for Quality (ANSI/ASQ Z1.4) tables and for retrieving variable
sampling plans from Military Standard (MIL-STD-414) - American National Standards Institute/American Society
for Quality (ANSI/ASQ Z1.9) tables. The sources for these tables are listed in the URL: field. Also included
are functions for computing the OC (Operating Characteristic) and ASN (Average Sample Number) coordinates
for the attribute plans it recalls, and functions for computing the estimated proportion nonconforming and
the maximum allowable proportion nonconforming for variable sampling plans. The MIL-STD AQL Sampling schemes
were the most used and copied set of standards in the world. They are intended to be used for sampling a stream
of lots, and were used in contract agreements between supplier and customer companies. When the US military
dropped support of MIL-STD 105E and 414, The American National Standards Institute (ANSI) and the International
Standards Organization (ISO) adopted the standard with few changes or no changes to the central tables. This
package is useful because its computer implementation of these tables duplicates that available in other
commercial software and subscription online calculators.
