ReliaGrowR (version 0.1.5)

rga: Reliability Growth Analysis.

Description

This function performs reliability growth analysis using the Crow-AMSAA model by Crow (1975) https://apps.dtic.mil/sti/citations/ADA020296 or piecewise NHPP model by Guo et al. (2010) doi:10.1109/RAMS.2010.5448029.

Usage

rga(
  times,
  failures,
  model_type = "Crow-AMSAA",
  breaks = NULL,
  conf_level = 0.95
)

Value

The function returns an object of class rga that contains the results for the model.

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.

model_type

The model type. Either Crow-AMSAA (default) or Piecewise NHPP with change point detection.

breaks

An optional vector of breakpoints for the Piecewise NHPP model.

conf_level

The desired confidence level, which defaults to 95%.

Examples

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