Units:
Billions of Chained 2012 Dollars, Seasonally Adjusted Annual Rate
Frequency:
Quarterly
Available Through:

Suggested Treatment:
The data shows auto correlation and a non-normal distribution. The data should be differenced. While the Untransformed transformation, provides the best normality, the Arcsin variable will also perform well.
Grain Transformation:
Data is unable to be distributed by time or geography. The roll up method used is Weighted Average.
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 -0.28
Trend Analysis:
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.08 p-value = 0.10 indicates that the data is stationary.
Distribution Analysis:
The Shapiro-Wilk test returned W = 0.95 with a p-value =0.07 indicating the data follows a normal distribution.
A skewness score of -0.01 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.04 with a p-value of 0.88 inidcates the data is unimodal
