# Data generated by autoregressive AR9 model.

### Description

Synthetically generated dataset containing values of dependent variable
`x_t`

given values of

`x_t-1, x_t-2, ..., x_t-15`

.

### Usage

1 |

### Format

A data frame with 1000 rows and 16 variables:

- x_t-1,x_t-2,x_t-3,x_t-4,x_t-5,x_t-6,x_t-7,x_t-8,x_t-9,x_t-10,x_t-11,x_t-12,
- x_t-13,x_t-14,x_t-15
lagged values of x_t in columns 1:15

- x_t
dependent variable in column 16

### Details

This dataset was generated using the AR9 model first described in Sharma (2000) and given by:

*
x_t = 0.3x_t-1 - 0.6x_t-4 - 0.5x_t-9 + ε_t*

where *ε_t*
