P_it: Iteration of p control chart for attributes

In XRSCC: Statistical Quality Control Simulation

Iteration of p control chart for attributes

Description

Calculates the iteration i'th for the control limits of p chart using the results obtained in p_gr or further P_it iterations.

Usage

P_it(prev.results)

Arguments

prev.results

Is a list of previous results obtained by the p_gr function. In other cases, needs more than one iteration, to obtain the true control limits for p chart before take conclusions about the process.

Value

in.control	The under control row list for the p chart in this iteration
out.control	The out of control row list for the p chart
Iteraciones	The number of iterations, It is assumed to be the second or later
data.n	The fixed sample size
data.0	The original data frame
data.1	The under control subset after iteration
bin	The binary values for out of control equal to one and under control equal to zero
Limites de Control Grafica \emph{p}	The p chart control limits vector
Conclusion del proceso	The same results in a phrase as the bin values
