Two Parameter Weibull Probability Plot

Wednesday, 1 November 2023, 10.47

Unweighted constrained simplex regression

Gradient:  1.0126        s.e. 0.0067
Intercept: -0.0966       s.e. 0.0463

Correlation Coefficient, r: 0.9973
Critical Value for r:       0.0334
Significance level used:    5.0%
Sum of squares:             62.3871

Best Estimates of the Parameters
sigma:  7.0092      'pseudo-linear' s.e. 0.0226
gamma:  2.1561      'pseudo-linear' s.e. 0.0164

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