If a time series displays an increasing trend and additive seasonal variation, the magnitude of the seasonal swing increases as time advances. Is this true or false?
This is not a homework question, it's just revision for my exam tomorrow, and I am unsure with this question.
I have another one:
When using Winter's Method, the multiplicative decomposition method is one of the techniques that can be used to determine the initial estimates needed to forecast a time series with multiplicative seasonal variation. Is this true or not?
