Binary observations
WebOct 20, 2024 · It is a binary (2-class) classification problem. The number of observations for each class is not balanced. There are 1,372 observations with 4 input variables and 1 output variable. The variable names are as follows: Variance of Wavelet Transformed image (continuous). Skewness of Wavelet Transformed image (continuous). WebJul 10, 2016 · I am trying to predict a binary target with True/False possible values. The dataset consists of 500 observations, 400 observation is False, and 100 observation is True. In order to avoid model bias, I wish to balance the distribution such that the dataset will consist of 100 False and 100 True observations.
