Businesses use real GDP figures to assess market demand, aiding in production planning and inventory management. Investors leverage this raw data to gauge economic resilience, guiding investment decisions. Economists use this metric to conduct in-depth analyses of economic cycles and trends, providing essential information for long-term economic forecasts. In essence, Real GDP, Total US (Not Seas Adj), offers a transparent window into the core of the U.S. economy, empowering stakeholders to make informed decisions in a rapidly changing economic landscape.

Grain Transformation:
Data is able to be distributed by time and geography. The roll up method used is Sum.
Auto Correlation Analysis:
Data shows auto correlation indicating a need for differencing
The ACF indicates 1 order differencing is appropriate.
Following first order differencing, no further differencing is required based on the differenced ACF at lag one of -0.34
Trend Analysis:
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.10 p-value = 0.10 indicates that the data is stationary.
Distribution Analysis:
The Shapiro-Wilk test returned W = 0.97 with a p-value =0.26 indicating the data follows a normal distribution.
A skewness score of 0.00 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.03 with a p-value of 0.99 inidcates the data is unimodal
