Point estimates are the single, most likely value of a parameter. For example, the point estimate of population mean (the parameter) is the sample mean (the parameter estimate). Confidence intervals are a range of values likely to contain the population parameter.

What are the parameters for estimation?

Parameter estimation in the field of atmospheric sciences refers to the determination of the best values of certain parameters in a numerical model through data assimilation or other similar techniques. The practice therefore is intimately tied to addressing model deficiencies due to inaccurate parameters.

Why do we estimate parameters?

The parameter values determine the location and shape of the curve on the plot of distribution, and each unique combination of parameter values produces a unique distribution curve. For example, a normal distribution is defined by two parameters, the mean and standard deviation.
