Performs Unit Root Test Statistics
Description
A test to understand the stability of the underlying
stochastic data. Helps the user<80><99>s understand whether the random variable under
consideration is stationary or non-stationary without any manual interpretation
of the results. It further ensures to check all the prerequisites and assumptions which
are underlying the unit root test statistics and if the underlying data is found to be non-stationary in all
the 4 lags the function diagnoses the input data and returns with an optimised solution on the same.
