People diagnosed with ALS live on average 2–4 years after diagnosis due to the quick progression of the disease. [2] [3] The progression and severity of ALS is rated by doctors on the ALS Functional Rating Scale, which has been revised and is referred to as ALSFRS-R.
The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.
It is a measure used to evaluate the performance of regression or forecasting models. It is a variant of MAPE in which the mean absolute percent errors is treated as a weighted arithmetic mean. Most commonly the absolute percent errors are weighted by the actuals (e.g. in case of sales forecasting, errors are weighted by sales volume). [3]
The Colley Matrix is most well known for ranking Central Florida ahead of Alabama in 2017 despite Alabama's victory in the 2017 College Football Playoff. [ 44 ] [ 45 ] Central Florida later proclaimed themselves as co-national champions because of the ranking, becoming the only school to claim a national championship based solely on the Colley ...
A Bayesian average is a method of estimating the mean of a population using outside information, especially a pre-existing belief, [1] which is factored into the calculation. This is a central feature of Bayesian interpretation. This is useful when the available data set is small. [2] Calculating the Bayesian average uses the prior mean m and a ...

For normally distributed random variables inverse-variance weighted averages can also be derived as the maximum likelihood estimate for the true value. Furthermore, from a Bayesian perspective the posterior distribution for the true value given normally distributed observations and a flat prior is a normal distribution with the inverse-variance weighted average as a mean and variance ().
