COVID-19 Pending Tests (State)
The COVID‑19 pandemic is an ongoing global pandemic of coronavirus disease 2019 (COVID‑19), caused by severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2). From the business focused data scientist there are three main measures to inform the economic impact- cases diagnosed, available hospital beds and recovered cases.
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 Boxcox variable will also perform well.
Data is unable to be distributed by time or geography. The roll up method used is Sum.
Pending Tests (State)
Auto Correction Function
Auto Correlation Function After Differencing
Partial Auto Correlation Function
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 = 0.15 p-value = 0.05 indicates that the data is not stationary.
The Shapiro-Wilk test returned W = 0.54 with a p-value =0.00 indicating the data does not follow a normal distribution.
A skewness score of 2.51 indicates the data are substantially skewed.
Hartigan's dip test score of 0.05 with a p-value of 0.07 inidcates the data is unimodal
Statistics (Pearson P/ df, lower => more normal)
