multivariate time series
  سری ِ زمانی ِ بسورتا   
seri-ye zamâni-ye basvartâ

Fr.: série temporelle multivariée   

A → time series consisting of two or more → univariate time series which share the same time period. As an example, if we record wind velocity and wind direction at the same instant of time, we have a multi-variate time series, specifically a bivariate one.

multivariate; → time; → series.

stationary time series
  سری ِ زمانی ِ ایست‌ور   
seri-ye zamâni-ye istvar

Fr.: série temporelle stationnaire   

A → time series if it obeys the following criteria: 1) Constant → mean over time (t). 2) Constant → variance for all t, and 3) The → autocovariance function between Xt1 and Xt2 only depends on the interval t1 and t2.

stationary; → time; → series.

time series
  سری ِ زمانی   
seri-ye zamâni

Fr.: série temporelle   

A → sequence of values of a → variable in successive time order, usually at fixed intervals of time.

time; → series.

univariate time series
  سری ِ زمانی ِ یکورتا   
seri-ye zamâni-ye yekvartâ

Fr.: série temporelle univariée   

A sequence of measurements of the same variable collected over time. Most often, the measurements are made at regular time intervals.

univariate; → time; → series.
