alloyc: Metal Alloy Tensile Strength Test

In Auburngrads/SMRD.data: Statistical Methods For Reliability Data - Datasets

Description

These data resulted from a test that was conducted to obtain information on the strength of an alloy produced by an alternate process. The designation for the alloy was not provided and is only referred to as "Alloy C". Specimens of the alloy were subjected to various levels of constant stress, measured in ksi (1 ksi = 1000 psi). The dataset includes the number of failed specimens observed in each interval of applied stress.

Format

A data.frame with 9 rows and 4 variables:

[, 1]	ksil	Lower limit of the stress interval	Numeric
[, 2]	ksiu	Upper limit of the stress interval	Numeric
[, 3]	event	Event observed in the interval (interval-censored)	Categoric
[, 4]	count	Number of events observed in the interval	Numeric
