plot_mds_n: Plot MDS Sample Size Against Termination Ratio

In rMDSPTT: Multiple Dependent State Sampling Inspection Plan for Time Truncated Life Test

Plot MDS Sample Size Against Termination Ratio

Description

Produces a base R plot of the minimum sample size against the termination ratio 'a'.

Usage

plot_mds_n(x, ...)

Arguments

x	Output from 'mds_asip()'.
...	Additional graphical arguments passed to 'plot()'.

Details

For the MDS plan considered here, ASN is exactly equal to the sample size 'n'. Therefore, the plot can also be interpreted as ASN against the termination ratio.

Value

Invisibly returns the supplied data frame.

Examples

# ----------------------------------------------------------
# Example 1: User-defined failure probabilities
# ----------------------------------------------------------
a <- c(0.5, 1, 1.5, 2)
p <- c(0.05, 0.10, 0.15, 0.20)

result <- mds_asip(
  p = p,
  a = a,
  b = 1,
  i = 3,
  beta = 0.25,
  c1 = 0,
  c2 = 1
)

plot_mds_n(result)

p <- ( 1- exp(-a / b))^alpha
