For this assignment you will work with the 'covid data,'which is a data set on daily covid cases acrossAustralia's states and territories, compiled by Covid Australia.I made some adjustments to the data, andcontains information on the daily number of covid cases and the daily administered covid tests (in thousands)a link to the working file in csv format will become available on Canvas.This csv file, called covid2.csvfor NSW only. For this part of the project ,you should do the following:

1. Using the series ranging from 6 June 2031 to 22' August 2021?, t the AR(1) model with a cubic trend component for 'cases' as well as 'tests' (note, because you will have to generate the lagged dependent variable, your e'ective data sample in the regressions will start from 7 June 2021). That is, you should estimate the following two equations: cases: = 510 + nmSest1 + 7113 + T12t2 + 71333: and tests: = 20 + agrem + 721: + 722:2 + 723:3. Obtain the persistence parameters. Enter the values of the persistence parameters, rounded to 2 decimal places, as answers to the second question of the onne quiz of this assignment
