The data shows auto correlation and a non-normal distribution. The data should be differenced. While the Square Root transformation, provides the best normality, the Untransformed variable will also perform well.
Data is unable to be distributed by time or geography. The roll up method used is Weighted Average.
Data shows auto correlation indicating a need for differencing
The ACF indicates 2 order differencing is appropriate.
Following first order differencing, no further differencing is required based on the differenced ACF at lag one of -0.27
The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.68 p-value = 0.01 indicates that the data is not stationary.
The Shapiro-Wilk test returned W = 0.95 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of 0.30 indicates the data are fairly symmetrical.
Hartigan's dip test score of 0.01 with a p-value of 1.00 inidcates the data is unimodal
