Hi,
In below post of Analytics Vidya, ANOVA test has been performed on COVID data, to check whether the difference in posotive cases of denser region is statistically significant.
I believe ANOVA test can’t be performed on this COVID time series data, atleast not in way as it has been done in this post.
Sample data has been consider randomly from different groups(denser1, denser2…denser4). The data is time series so it is more likely that number of positive cases in random sample of groups will be from different point of time.
There might be the case denser1 has random data from early covid time and another region has random data from another point of time. If this is the case, then F-Statistics will high certainly.
Can anyone explain if you have other opinions?
