Two Parameter Weibull Probability Plot

Wednesday, 22 May 2024, 15.41

Unweighted constrained simplex regression

Gradient:  1.0089        s.e. 0.0024
Intercept: -0.0709       s.e. 0.0175

Correlation Coefficient, r: 0.9965
Critical Value for r:       0.0119
Significance level used:    5.0%
Sum of squares:             613.3209

Best Estimates of the Parameters
sigma:  7.4932      'pseudo-linear' s.e. 0.0079
gamma:  2.357       'pseudo-linear' s.e. 0.0065

The 'pseudo-linear' s.e.s are a lower limit to the s.e. and may significantly underestimate the s.e.
