Imsl.Chart2D.QC Namespace
The Imsl.Chart2D.QC namespace contains a variety of quality control charts used to monitor business and manufacturing processes.
Classes
  ClassDescription
Public classCChart
CChart is a c-chart for monitoring the count of the number of defects when defects are rare. Control limits are computed using the Poisson distribution. If defects are not rare NpChart should be used instead.
Public classControlLimit
ControlLimit is a control limit line on a process control chart.
Public classCuSum
CuSum is a cumulative sum chart. It is more efficient than a Shewhart chart for detecting small shifts in the mean of a process.
Public classCuSumStatus
CuSumStatus is a cumulative sum status chart. CuSumStatus plots the tabular CuSum results.
Public classEWMA
EWMA is an exponentially weighted moving average control chart.
Public classNpChart
NpChart is an np-chart for monitoring the number of defects when defects are not rare.
Public classParetoChart
ParetoChart is a Pareto bar chart.
Public classPChart
PChart is a p-chart for monitoring the defect rate when defects are not rare.
Public classRChart
RChart is an R chart using sample ranges to monitor the variability of a process. Each sample must contain at least two observations. The range of a sample is the maximum observed value minus the minimum observed value.
Public classSChart
SChart is an S chart using sample standard deviations to monitor the variability of a process. This is normally used with sample sizes greater than 10.
Public classShewhartControlChart
ShewhartControlChart is the base class for the Shewhart control charts.
Public classUChart
UChart is a u-chart for monitoring the defect rate when defects are rare.
Public classXbarR
XbarR is an X-bar chart for monitoring a process using sample ranges.
Public classXbarS
XbarS is an X-bar chart for monitoring a process using sample standard deviations.
Public classXmR
XmR is an XmR chart for monitoring a process using moving ranges.
