datasets_for_debugging: Synthetic Datasets, for Demo's and Debugging 'abrem' .
In abrem: Abernethy Reliability Methods

A collection of synthetic datasets for debugging the abrem package, created using the params.to.ob function. When these datasets are fitted with a two-parameter Weibull distribution using X-on-Y rank regression on exact 'median' plotting positions, the resulting parameters beta and eta are (almost) exactly 3 and 1000, respectively.

    abrem3
    abrem13
    abrem13c1
    abrem13c2
    abrem13c3
    abrem13c4

An ordered dataframe with columns $time ((life-)time observations) and $event (censoring indicators).

All datasets have comments; see comment for more info.

abrem2: Two failures, no censoring.
abrem3: Three failures, no censoring.
abrem13: Thirteen failures, no censoring.
abrem13c1: Type II censored dataset with 13 observations: two failures and 11 suspensions (at the same time as the latest failure).
abrem13c2: Type II censored dataset with 13 observations: three failures and 10 suspensions (at the same time as the latest failure).
abrem13c3: Type II censored dataset with 13 observations: ten failures and three suspensions (at the same time as the latest failure).
abrem13c4: Type II censored dataset with 13 observations: 12 failures and one suspension (at the same time as the latest failure).

The observations in this dataset are rounded output values from params.to.ob. Even higher precision can be achived by using the output of params.to.ob directly, as evidenced by comparing the goodness-of-fit indicators from both fits.
