Sentences with phrase «good measure of the uncertainty»

At the fundamental publishing level I see a lack of or maybe even an avoidance of doing the required sensitivity testing that can give a better measure of the uncertainty involved.

With nonstationary statistics the standard error of the fit over past years is not a good measure of the uncertainty in the prediction.

Not exact matches

We also welcome measures to reduce uncertainty to business at a time of fragile economic recovery — so a move to only call for a referendum if certain and well understood conditions are not met is helpful.

Equally striking, if less well known, are the so - called squeezed quantum states: Normally, Heisenberg's uncertainty principle means that one can not measure the values of certain pairs of physical quantities, such as the position and velocity of a quantum particle, with arbitrary precision.

A separate experiment measuring the atoms in a silicon sphere has calculated Planck's constant down to an uncertainty of 20 parts per billion, while the best watt measurement has achieved an uncertainty of just 19 parts per billion.

«We've done the world's best job of decreasing the uncertainty in the measured rate of universal expansion and of accurately assessing the size of this uncertainty,» said Filippenko, «yet we find that our measured rate of expansion is probably incompatible with the rate expected from observations of the young universe, suggesting that there's something important missing in our physical understanding of the universe.»

Fewer studies share effect sizes (which arguably gives a better indication of how meaningful a result might be) or discuss measures of uncertainty.

We also use state - of - the - art quality checking and measuring techniques to ensure that the clients get best options when they queue up with us to buy dissertations online without any trace of uncertainty.

[Response: Dropping outliers just because they don't agree with your preconceived ideas is a classical error in statistics — it's much better to use the spread as a measure of the uncertainty.

Gavin, You wrote: - «Dropping outliers just because they don't agree with your preconceived ideas is a classical error in statistics — it's much better to use the spread as a measure of the uncertainty.

The skin temperature can be measured with absolute uncertainties of much less than 0.1 ºK The thermometer in the surface following float is accurate to better than 0.01 ºK.

Far better this than running a dozen GCMs with funamentally different assumptions about climate feedbacks, plotting them on a graph and claiming that as a measure of the uncertainty in the behaviour of the real climate.

Better description of uncertainty would certainly help, both observationally (the Schmidt 2015 hottest evah fiasco is a specific example), and concerning models (the Christy chart of the actual tropical troposphere as measured by ballons and satellites versus CMIP5 is an example).

Regarding land use run 1, Gavin at Real Climate says: «Dropping outliers just because they don't agree with your preconceived ideas is a classical error in statistics — it's much better to use the spread as a measure of the uncertainty»

Perhaps all measures would be better put on hold for an iteration and an agreed programme of uncertainty reduction taken as a matter of urgency.

The data set also depends on the correct assessment of two other aspects of sea level rise and hence is an indirect measure... [It] is a good approach, but with high uncertainties at present.

The challenges are finding a good enough measure of urbanity, dealing with uncertainty in station locations (a problem in many areas outside the U.S., where lat / lon coordinates aren't always accurate), and ensuring that your method doesn't suffer from spatial coverage biases between urban and rural sets (I tend to prefer station pair comparison methods for that reason).

Call me cynical if you like, but if Judith had wanted to create a measure of uncertainty and doubt in the popular mind about the BEST findings, then allowing the Daily Mail to do their worst with her comments would be a neat and deniable way of doing it, don't you think?

It is good, as SteveM notes in this thread, that scientists have taken another look at the SST uncertainties and biases, but reading from the article (see comment in quotes below) one still comes away with a sense that we have no final hard and fast objective measure of the uncertainties in the temperature measurements.

Here Ravetz might have confused the sensitivity for CO2 doubling per se which is well established at ~ 1C, with the more usual measure of climate sensitivity taking into account all feedbacks, which is necessarily a more uncertain enterprise, but usually considered to be around 3C, albeit with much broader uncertainty.

Using an ensemble of eight models calibrated only for phenology or five models calibrated in detail resulted in the uncertainty equivalent to that of the measured yield in well - controlled agronomic field experiments.

Independent agents will help take the fear and uncertainty out of shopping for life insurance, and can help you take measures to get the best coverage possible for your needs.
