Open SAS Studio create a new program and run the following code

$/*$ the following $3$ lines of code assign all the CAS libraries and lists the into the log window$*/$

cas mySession sessopts$=($caslib$=$casuser timeout$=1800$ locale$="$en$\_$US$")$;

caslib $\_$all$\_$ list;

caslib $\_$all$\_$ assign;

locate the PRICEDATA data set from the following library SASHELP.

Run a proc contents to explore the data set.

Complete $($Questions $1-6)$ using proc contents and proc freq or proc sql$.$

Promote the PRICEDATA data set into CASUSER CAS library. You can run the following code;

$/*$ you can name this whatever you wan but library must be casuser$*/$

$/*$ we need to promote the pricedata into CAS to access by Visual Forecasting$*/$

data casuser.somedatasetname $($promote$=$yes$)$;

set sashelp.pricedata;

run;

Verify that the data set you created above is in the CASUSER library

Open Viya Model Studio and create a forecast project using the autoforecast

Use the following procedures; Variable for Date$-$time, Time Interval is month, Multiplier $=1$ and shift $=1.$

Create a seasonal model and a na$$ve model by right clicking data node and create forecast.

Choose WMAPE as a metric to declare a model champion

Create an override and submit

How many observations are there in the data set $(1$ mark$)?$

How many Variables are in the data set $(1$ mark$)?$

What is the unit of time for this forecast $(2$ marks$)?$

How many unique time periods are there $(2$ marks$)?$

What is the earliest time period $(2$ marks$)?$

What month did the largest Sales volume occur $(2$ marks$)?$

What is the predicted sales value of; REGION$=1,$ LINE$=1,$ and PRODUCT$=2$ for May $03(2$ marks$)?$

What model was most prevalent in the Auto Forecasting $($Marks$=2)?$

What was the upper confidence interval value for Jun$03$ for Line $5$ Product $16(2$ marks$)?$

What model was the champion model between seasonal$/$autoforecasting$/$na$$ve $(2$ marks$)?$

Display the predicted values series with the following override: the sales in March $03$ were going to be $$10,000(2$ marks$)?$
