## Automated Data Profiling

Ready Signal automatically profiles each data set and offers up suggested industry standard data science treatments to utilize with these data in your models.

### Suggested Treatment:

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

### Grain Transformation:

Data is unable to be distributed by time or geography. The roll up method used is Weighted Average.

### Auto Correlation Analysis:

Data shows auto correlation 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 -0.28

### Trend Analysis:

The Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, KPSS Trend = 0.08 p-value = 0.10 indicates that the data is stationary.

### Distribution Analysis:

The Shapiro-Wilk test returned W = 0.95 with a p-value =0.07 indicating the data follows a normal distribution.

A skewness score of -0.01 indicates the data are fairly symmetrical.

Hartigan's dip test score of 0.04 with a p-value of 0.88 inidcates the data is unimodal
