The Weibull parameter (beta) is the slope. It signifies the rate of failure. When < 1, the Weibull distribution models early failures of parts. When = 1, the Weibull distribution models the exponential distribution. The exponential distribution is the model for the useful life period, signifying that random failures are occurring. When = 3, the

Procedures for estimation of Weibull parameters

Weibull distribution is occuring as wood construction practices in the United States and Canada are revised from deterministic procedures to reliability-based design (RBD) procedures. The two-parameter Weibull distribution is the underlying basis of the calculations in load and resistance

A Statistical Distribution Function of Wide Applicability

WEIBULL-ASTATISTICAL DISTRIBUTION FUNCTION OF WIDE APPLICABILITY 297 Ifthe classes 17-18are pooled, the value of X' - 4.50, and the doff9 - 31/, - 51/ , give a P - 0.56. It may be of interest to compare this result with those of Charlier and Crama-.

Weibull distribution. In the current example, the P-Value is large, suggesting that the Weibull distribution is a reasonable model for the data. The goodness-of-fit tests are described in detail for uncensored in the documentation for Distribution Fitting (Uncensored Data) and for censored data in Distribution Fitting (Censored Data.
