How do you summarize a time series data in R?
To summarize data by a particular variable or time period, you first create a new column in your dataset called day. Next, take all of the values (in this case precipitation measured each hour) for each day and add them using the sum() function. You can do all of this efficiently using dplyr mutate() function.
What is forecasting and its techniques?
Forecasting is a technique that uses historical data as inputs to make informed estimates that are predictive in determining the direction of future trends. Businesses utilize forecasting to determine how to allocate their budgets or plan for anticipated expenses for an upcoming period of time.
What is the purpose of aggregation?
Aggregate functions deliver a single number to represent a larger data set. The numbers being used may themselves be products of aggregate functions. Many descriptive statistics are the result of aggregate functions. Economists use the outputs of data aggregation to plot changes over time and project future trends.
