MVPspc is an easy-to-use SPC (Statistical Process Control) charting and analysis program. This program is extremely flexible, providing analysis not available in any other SPC package. The program uses simple text files, or you may copy and paste directly from a spread sheet. Control limits calculations can be generated numerous ways. For example, a Range chart can use the average range, the median range, the average standard deviation, the median standard deviation, the average variance, the average moving range of the ranges, the median moving range of the ranges, the standard deviation of the ranges, or from a know standard deviation. Attributes charts can use approximate or exact control limits. Capability/Performance routines allow you to test alternative distribution fits. Process Performance Analysis can also be obtained with this software. This is a great off-line SPC package for students, teachers, quality engineers and industrial researchers.
