Setar (Persian: سهتار, from seh, meaning "three" and tār, meaning "string") is a Persian musical instrument. It is a member of the lute family, which is played with index finger of the right hand. Two and a half centuries ago, a fourth string was added to the setar. it has 25 - 27 moveable frets which are usually made of animal intestines or silk. It originated in Persia before the spread of Islam.

In statistics, Self-Exciting Threshold AutoRegressive (SETAR) models are typically applied to time series data as an extension of autoregressive models, in order to allow for higher degree of flexibility in model parameters through a regime switching behaviour.
Given a time series of data xt, the SETAR model is a tool for understanding and, perhaps, predicting future values in this series, assuming that the behaviour of the series changes once the series enters a different regime. The switch from one regime to another depends on the past values of the x series (hence the Self-Exciting portion of the name).
The model consists of k autoregressive (AR) parts, each for a different regime. The model is usually referred to as the SETAR(k, p) model where k is the number of regimes and p is the order of the autoregressive part (since those can differ between regimes, the p portion is sometimes dropped and models are denoted simply as SETAR(k).
Consider a simple AR(p) model for a time series yt
Staring at the ideal world,
The bubble begins to break,
Gazing at the ceiling cracks,
The more the picture fades,
It's just that i can't see,
When im down like this,
I just feel the wieght,
As i try to resist.
It doesn't matter when i dream away,
Life in a Stereo World,
Something happens, i Drift away (away)
Floating out of sync again,
Reaching for a cloud,
Levitating high, i'm free,
Turning myself around,
Just as i feel fine,
It begins to break,
Now the pain is here,
What a big mistake.
It just explodes as i drift in,
A thousand hands caress my skin,
