The ASA physical status classification system is a system for assessing the fitness of patients before surgery. In 1963 the American Society of Anesthesiologists (ASA) adopted the five-category physical status classification system; a sixth category was later added. These are:
[3] [2] According to the Fast Facts for the Triage Nurse handbook, the ESI algorithm is primarily used in the United States. [2] As of 2019, 94% of United States EDs use the ESI algorithm in triage. [1] The concept of a "resource" in ESI means types of interventions or diagnostic tools, above and beyond physical examination.
In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. [16] [17] [18] The NEWS score is the largest national EWS effort to date and has been adopted by some international healthcare services. [1] A second version of the score was introduced in 2017.

These models are useful in modeling time series with long memory—that is, in which deviations from the long-run mean decay more slowly than an exponential decay. The acronyms "ARFIMA" or "FARIMA" are often used, although it is also conventional to simply extend the "ARIMA( p , d , q )" notation for models, by simply allowing the order of ...
The CRAN task view on Time Series is the reference with many more links. The "forecast" package in R can automatically select an ARIMA model for a given time series with the auto.arima() function [that can often give questionable results] and can also simulate seasonal and non-seasonal ARIMA models with its simulate.Arima() function. [16]
An additive model would be used when the variations around the trend do not vary with the level of the time series whereas a multiplicative model would be appropriate if the trend is proportional to the level of the time series. [3] Sometimes the trend and cyclical components are grouped into one, called the trend-cycle component.
Partial autocorrelation function of Lake Huron's depth with confidence interval (in blue, plotted around 0). In time series analysis, the partial autocorrelation function (PACF) gives the partial correlation of a stationary time series with its own lagged values, regressed the values of the time series at all shorter lags.
