Industrial Production and Capacity Utilization
Index 2012=100, Seasonally Adjusted
The industrial production index is an economic indicator that measures the real production output of manufacturing, mining, and utilities. This is indicative of the overall economic situation and GDP in the United States.
The data shows autocorrection and a non-normal distribution. The data should be differenced. While the Order Norm transformation, provides the best normality, the Yeo Johnson variable will also perform well.
Data is unable to be distributed by time or geography. The roll up method used is Weighted Average.

Partial Auto Correlation Function
Seasonal and Trend Decompostion
Data shows autocorrectation indicating a need for differencing
The ACF indicates 1 order differencing is appropriate.
Further differencing is reccommended
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.33 p-value = 0.01 indicates that the data is not stationary.
The Shapiro-Wilk test returned W = 0.94 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of 0.37 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.04 with a p-value of 0.19 inidcates the data is unimodal
