The following assumptions were applied to calculate the trends for this model
- Firstly note that this is the original first draft of the Rt model. The 'second' model on the home page takes more variables into consideration for the country's trend.
- Applies to provincial Rt plots.
- Smoothed average data is used.
- The error bands, indicating the 90% credibility interval, has temporary been removed.
- For regions with low case rates, only the date ranges with the most significant change is shown.
- The lag time between testing and positive case identification is not taken into account, due to the difficulty to obtain access to testing data for regions.
