Background of the case

During the year 2018, the Canadian Goverment received an appeal that prisioners were being wrongfully convicted and the issue gained mass amounts of traction. Thus, the government appointed a team to look into the issue by conducting lie detector tests on 1372 prisoners across various states and provinces of the country. The team has done the basic checks and accordingly given the Variance, Skewness, Kurtosis and Entropy of the Responses obtained by the lie detector test. These are predictors for the Dependent Variable which states whether the response being considered belongs to a liar or not a liar. (These variables are to be treated as Independent Variables only, and no variance, skewness, kurtosis, entropy needs to be calculated for the analysis.)

Data Dictionary

The dataset consists of the following variables:

1. X1 : Prisoner ID
2. X2 : Variance of responses obtained.
3. X3 : Skewness of responses obtained.
4. X4 : Kurtosis of responses obtained.
5. X5 : Entropy of responses.
6. X6 : Class of person, 0 means the person is not a liar, and 1 means that the person is a liar.
