Of course, as the model has a bad performance I cannot assure that out-of-sample predictions would be accurate. To interpret the test results, you only need to look at the p value. And you use the following simple method: It’s not a hard and fast rule, but a stationary data should have a small p value. Larger p value could indicate presence of certain trends (varying mean) or seasonality as well. In the project, two datasets are provided, each consists of one week of air quality sensor readings. From looking at the graph, there is a "zig-zag" type of pattern, where we see only one change in trend to the upside and the pattern continues as normal.
