Available Through:

Why Use:

Civilian labor force by US state measures the number of persons 16 years of age or older, employed or unemployed, excluding military personnel, federal government employees, retirees, handicapped or discouraged workers, and agricultural workers. This indicates state populations and can influence employment or unemployment rates.

Suggested Treatment:

The data shows autocorrection and a non-normal distribution. The data should be differenced. While the Order Norm transformation, provides the best normality, the Arcsin variable will also perform well.

Grain Transformation:

Data is able to be distributed by time but not by geography. The roll up method used is Sum.

Autocorrectation Analysis:

Data shows autocorrectation indicating a need for differencing

The ACF indicates 1 order differencing is appropriate.

Further differencing is reccommended

Trend Analysis:

The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.19 p-value = 0.02 indicates that the data is not stationary.

Distribution Analysis:

The Shapiro-Wilk test returned W = 0.91 with a p-value =0.00 indicating the data does not follow a normal distribution.

A skewness score of -0.05 indicates the data are fairly symmetrical.

Hartigan's dip test score of 0.09 with a p-value of 0.00 inidcates the data is multimodal
