@SebastianSolidwork @nobsagile An T-Shirt-Größen mag ich, dass sich jeder was drunter vorstellen kann, und vor allem, dass sie sich „gleichabständig“ anfühlen. Und die vier Größen S, M, L, XL lassen sich mit der Stacey-Matrix (einfach, kompliziert, komplex, chaotisch) wieder in qualitative Bilder übersetzen, bei denen niemand auf die Idee kommt, sie in Stunden gießen zu wollen. Dann kann man auch mal sagen, „komm, wir nehmen noch zwei kleine S mit mit rein.“ — #storypoints #tshirt #estimate

Global Performance of #RemoteSensing Based and Reanalysis-Driven Models to Estimate Open Water Evaporation

“ABSTRACT: Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation. Although several remote sensing algorithms have been providing evaporation estimates, the lack of a global validation hinders our understanding of their relative uncertainties and performances across different regions. Here, [they] analyze[d] the performance of a suite of models that leverage satellite data and meteorological reanalysis to estimate evaporation over lakes worldwide. [They] compare[d] three remote sensing-based models, one reanalysis-driven model and one ensemble approach, using in situ observations from 27 lakes representing a diverse range of geographic and climatic regions. [Their] results demonstrate that, overall, the ensemble outperformed any individual model in terms of accuracy, with a RMSE and a bias of 1.3 and 0.3 mm/day, respectively. These findings highlight the benefits of using an ensemble approach to estimate open water evaporation with satellite-based models at the global scale, leveraging the unique strengths of each model. For the individual models, differences in the representation of heat storage changes and advection effects led to lower values of RMSE and bias, depending on the location and depth of the lakes. This study sets the path for future improvement of open water evaporation algorithms globally, while remote sensing techniques are proven satisfactory to monitoring of water loss in lakes globally, an essential step toward effective large-scale water resources management.
PLAIN LANGUAGE SUMMARY: Water loss through evaporation in lakes and reservoirs directly affects water availability, which highlights the need to monitor these losses. However, measuring evaporation in situ is challenging and expensive. An alternative is to estimate evaporation using remote-sensing models and compare these estimates with in-situ data to verify their accuracy. Here, [they] evaluated four models and their ensemble (the models' mean value) using measurements from 27 lakes and reservoirs worldwide. [They] found that the ensemble presented higher accuracy and consistency than any individual model because it benefits from the strengths of each model. This approach can guide future improvements in estimating open-water evaporation, which is essential for large-scale water-resource management…”

@dectentoo re-estimation is not quite the same as ‘learning and adapting’. It involves agreeing that ‘more time is needed’, and is only #agile if the reasons behind the new #estimate are tackled as a result of the learning process.

"A p-value is an #estimate of p(Data | Null Hypothesis). " – not correct. A p-value is an estimate of
p(Data or other imagined data | Null Hypothesis)
so not even just of the actual data you have. Which is why p-values depend on your stopping rule (and do not satisfy the "likelihood principle"). In this regard, see Jeffreys's quote below.
Imagine you design an experiment this way: "I'll test 10 subjects, and in the meantime I apply for a grant. At the time the 10th subject is tested, I'll know my application's outcome. If the outcome is positive, I'll test 10 more subjects; if it isn't, I'll stop". Not an unrealistic situation.
With this stopping rule, your p-value will depend on the probability that you get the grant. This is not a joke.
"*What the use of P implies, therefore, is that a hypothesis that may be true may be rejected because it has not predicted observable results that have not occurred.* This seems a remarkable procedure. On the face of it the fact that such results have not occurred might more reasonably be taken as evidence for the law, not against it." – H. Jeffreys, "Theory of Probability" § VII.7.2 (emphasis in the original) <https://doi.org/10.1093/oso/9780198503682.001.0001>.

@paninid p-values, to a large extent, exist because calculating the posterior is computationally expensive. Not all fields use the .05 cutoff.
A p-value is an #estimate of p(Data | Null Hypothesis). If the two #hypotheses are equally likely and they are mutually exclusive and they are closed over the #hypothesis space, then this is the same as p(Hypothesis | Data).
Meaning, under certain assumption, the p-value does represent the actually probability of being wrong.
However, given modern computers, there is no reason that #Bayesian odds-ratios can't completely replace their usage and avoid the many many problems with p-values.

#Etsy gave the #buyer an estimated delivery date of 5 January.
Despite the #holiday rush, when #packages are always slower, despite the #holidays when Canada Post and others are closed, they provided him an estimate right at the bottom end of that "official" #estimate.
And then, the buyer will probably (rightly) be angry when it takes until February, because Etsy promised it on 5 January.
And they don't provide a way to override the estimate they display.

INSTEAD: Ask a developer "Have you got enough information about this to get started?" and their answer will be "yes" even when the requirement is vague.
