In ReliaGrowR: Reliability Growth Analysis

Duane Analysis.

Description

This function performs a Duane analysis (1962) doi:10.1109/TA.1964.4319640 on the provided failure data.

Usage

duane_plot(
  times,
  failures,
  plot = TRUE,
  log = TRUE,
  point_col = "black",
  line_col = "black",
  xlab = "Cumulative Time",
  ylab = "Cumulative MTBF",
  main = "Duane Plot with Cumulative MTBF"
)

Arguments

times	A vector of cumulative times at which failures occurred.
failures	A vector of the number of failures at each corresponding time in times.
plot	Show Duane plot (TRUE) or hide plot (FALSE).
log	Logical indicating whether to use logarithmic scale for the plot (default: TRUE).
point_col	Color for the data points (default: "black").
line_col	Color for the fitted line (default: "black").
xlab	Label for the x-axis (default: "Cumulative Time").
ylab	Label for the y-axis (default: "Cumulative MTBF").
main	Title for the plot (default: "Duane Plot with Cumulative MTBF").

Value

A list containing the fitted model, AIC, and BIC.

Examples

times <- c(100, 200, 300, 400, 500)
failures <- c(1, 2, 1, 3, 2)
fit <- duane_plot(times, failures)
print(fit)
