# Chronic Kidney Disease

#Context
This dataset is originally from UCI Machine Learning Repository. The objective of the dataset is to diagnostically predict whether a patient is having chronic kidney disease or not, based on certain diagnostic measurements included in the dataset.

#Content
The datasets consists of several medical predictor variables and one target variable, Class. Predictor variables includes Blood Pressure(Bp), Albumin(Al), etc.

#Inspiration
Can you build a machine learning model to accurately predict whether or not the patients in the dataset have chronic kidney disease or not?
