Released 2023-10-19
v2.8 What's new
1. NEW: Data transformations.
Specific columns of the dataset can be modified utilizing various straightforward functions: Standardize, Normalize, Logarithm, Exponential, Reciprocal; Root, and Angular transformations.
Appreciation is extended to Prof. Zhengtang Guo for his invaluable suggestions.
2. NEW: Column manipulate.
Designated columns from the chosen datasets can be combined using a specified weight.
Special thanks to Prof. Zhengtang Guo for his invaluable suggestions.
3. NEW: Moving Average - Fixed Bandwidth.
