In Part 1 I covered the exploratory data analysis of a time series using Python & R and in Part 2 I created various forecasting models, explained their differences and finally talked about forecast uncertainty. A power transform removes a shift from a data distribution to make the distribution more-normal (Gaussian).. On a time series dataset, this can have the effect of removing a change in variance over time. A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form.
