Two Parameter Weibull Probability Plot

Monday, 22 January 2024, 9.36

Unweighted constrained simplex regression

Gradient:  1.0123        s.e. 0.1434
Intercept: -0.1064       s.e. 1.2217

Correlation Coefficient, r: 0.9547
Critical Value for r:       0.3365
Significance level used:    5.0%
Sum of squares:             2.3631

Best Estimates of the Parameters
sigma:  8.9982      'pseudo-linear' s.e. 0.2148
gamma:  6.619       'pseudo-linear' s.e. 0.9988

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