Plot with random data showing homoscedasticity: at each value of x, the y-value of the dots has about the same variance. Plot with random data showing heteroscedasticity: The variance of the y-values of the dots increases with increasing values of x.
Stata includes the function arima. for ARMA and ARIMA models. SuanShu is a Java library of numerical methods that implements univariate/multivariate ARMA, ARIMA, ARMAX, etc models, documented in "SuanShu, a Java numerical and statistical library". SAS has an econometric package, ETS, that estimates ARIMA models. See details.
The goal is then to predict which disease is causing the observed liver-related symptoms in a new patient. The observed outcomes are the party chosen by a set of people in an election, and the explanatory variables are the demographic characteristics of each person (e.g. sex, race, age, income, etc.).
Prediction intervals are commonly used as definitions of reference ranges, such as reference ranges for blood tests to give an idea of whether a blood test is normal or not. For this purpose, the most commonly used prediction interval is the 95% prediction interval, and a reference range based on it can be called a standard reference range.
This list of protein subcellular localisation prediction tools includes software, databases, and web services that are used for protein subcellular localization prediction. Some tools are included that are commonly used to infer location through predicted structural properties, such as signal peptide or transmembrane helices , and these tools ...

Stata includes ARIMA modelling (using its arima command) as of Stata 9. StatSim: includes ARIMA models in the Forecast web app. Teradata Vantage has the ARIMA function as part of its machine learning engine. TOL (Time Oriented Language) is designed to model ARIMA models (including SARIMA, ARIMAX and DSARIMAX variants) .
In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one [clarification needed] effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values ...
