Written using Python, which is suitable for operating systems, e.g., Windows/Linux/MAC OS etc.

## Installing

pip install TCLR

## Updating

pip install –upgrade TCLR

## Running

` from TCLR import TCLRalgorithm as model dataSet = "testdata.csv" # dataset name correlation = 'PearsonR(+)' minsize, threshold, mininc = 3, 0.9, 0.01 model.start(dataSet, correlation, minsize, threshold, mininc, gplearn = True) `

output: + classification structure tree in pdf format（Result of TCLR.pdf) + a folder called ‘Segmented’ for saving the subdataset of each leaf (passed test)

note:

the complete execution template can be downloaded at the Source Code folder

graphviz (recommended installation) package is needed for generating the graphical results, which can be downloaded from the official website http://www.graphviz.org/. see user guide.

## Update log TCLR V1.1 April, 2022. debug and print out the slopes when Pearson is used
