Initial Unemployment Claims
Number, Not Seasonally Adjusted
Weekly, Ending Saturday
Initial claims by state measures the number of unemployment claims filed per week in each US state. This is indicative of overall economic health, availability of jobs, and economic resessions/depressions.
The data shows autocorrection, seasonality and a non-normal distribution. The data should be differenced and seasonally adjusted. While the Order Norm transformation, provides the best normality, the Arcsin variable will also perform well.
Data is able to be distributed by time but not by geography. The roll up method used is Sum.

Auto Correction Function
Auto Correlation Function After Differencing
Partial Auto Correlation Function
Seasonal and Trend Decompostion
Data shows autocorrectation 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 -0.25
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.07 p-value = 0.10 indicates that the data is stationary.
The Shapiro-Wilk test returned W = 0.86 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of 1.83 indicates the data are substantially skewed.
Hartigan's dip test score of 0.01 with a p-value of 0.87 inidcates the data is unimodal
