Sometimes that’s easy to figure out. For example, with small populations, you usually have a parameter because the groups are small enough to measure: Examples of parameters: 10% ofUS senatorsvoted for a particular measure. There are only 100 US Senators, you can count what every s...
CIs use sample data to present a range of values that incorporates a margin of error around the point estimate. This range of values is where the unknown parameter is likely to fall.
Statistic vs. Parameter. A parameter isdata about an entire population.For example, if you want to find out which classes freshmen at a certain college were taking, you could ask everyone (perhaps via email) and it would be possible to get a parameter. Statistics are when you base your da...
As we’ve seen above, the normal distribution has many different shapes depending on the parameter values. However, the standard normal distribution is a special case of the normal distribution where the mean is zero and the standard deviation is 1. This distribution is also known as the Z-di...

Orthodoxians trying to understand Bayesian methods have been caught in a semantic trap by their habitual use of the phrase “distribution of the parameter” when one should have said “distribution of the probability”. Bayesians had supposed this to be merely a figure of speech;i.e.,that th...
If we have parameter uncertainty (see Ensemble Forecasting) this means we also have to run simulations over the spread of parameters. Here’s my suggested alternative of the initial value vs boundary value problem: Figure 3 So one body made an ad hoc definition of climate as the 30-year ...
