Economic data are data describing an actual economy, past or present.These are typically found in time-series form, that is, covering more than one time period (say the monthly unemployment rate for the last five years) or in cross-sectional data in one time period (say for consumption and income levels for sample households).
Time series analysis comprises methods for analyzing time series data in order to extract meaningful statistics and other characteristics of the data. Time series forecasting is the use of a model to predict future values based on previously observed values. Generally, time series data is modelled as a stochastic process.
High frequency data employs the collection of a large sum of data over a time series, and as such the frequency of single data collection tends to be spaced out in irregular patterns over time. This is especially clear in financial market analysis, where transactions may occur in sequence, or after a prolonged period of inactivity. [7]
The economic data published on FRED are widely reported in the media and play a key role in financial markets. In a 2012 Business Insider article titled "The Most Amazing Economics Website in the World", Joe Weisenthal quoted Paul Krugman as saying: "I think just about everyone doing short-order research — trying to make sense of economic issues in more or less real time — has become a ...
For example, in economics a regression to explain and predict money demand (how much people choose to hold in the form of the most liquid assets) could be conducted with either cross-sectional or time series data. A cross-sectional regression would have as each data point an observation on a particular individual's money holdings, income, and ...
A wage price series is a set of data claiming to indicate the real wages and real prices of goods over a span of time, and their relationship to each other through the price of money at the time they were compared. Wage price series are currently collected and computed by major governments. Wage price series are also computed historically by ...
Cross-sectional data differs from time series data, in which the same small-scale or aggregate entity is observed at various points in time. Another type of data, panel data (or longitudinal data), combines both cross-sectional and time series data aspects and looks at how the subjects (firms, individuals, etc.) change over a time series. Panel ...
When time series data has seasonality removed from it, it is said to be directly seasonally adjusted. If it is made up of a sum or index aggregation of time series which have been seasonally adjusted, it is said to have been indirectly seasonally adjusted. Indirect seasonal adjustment is used for large components of GDP which are made up of ...
