Two Parameter Weibull Probability Plot

Thursday, 18 August 2022, 9.20

Unweighted constrained simplex regression

Gradient:  1.0259        s.e. 0.001
Intercept: -0.2705       s.e. 0.0098

Correlation Coefficient, r: 0.9941
Critical Value for r:       0.0072
Significance level used:    5.0%
Sum of squares:             5771.7308

Best Estimates of the Parameters
sigma:  9.4273      'pseudo-linear' s.e. 0.0049
gamma:  2.0973      'pseudo-linear' s.e. 0.0025

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