What is Project about?
Hypothesis
H0: There is no association of one unit increase in blood pressure with chronic kidney disease.
H1: There is association of one unit increase in blood pressure with chronic kidney disease.
Our database
Source: http://archive.ics.uci.edu
Variables:
We use Pus Cell, Age, and Blood Pressure to estimate the effect on the Chronic Kidney disease database.
1- Age
2- Blood Pressure:
- Blood Pressure: Low : 80 or less
- Blood Pressure: Mid : 80- 120
- Blood Pressure: High : 120 or Above
3- Pus Cell: It consists of a buildup of dead, white blood cells that form when the body’s immune system responds to the infection
4- Class: CKD =1, NotCKD=0
Class of the Chronic Kidney Disease :
Chronic Kidney Disease Class by Pus Cell:
Blood Pressure by the Chronic Kidney Disease:
Chronic Kidney Disease by Age:
Ready to apply for logistic Regression
Our Result is :
Because the P-value is clearly less than a = 0.05, we reject H0 and conclude that high blood pressure and Chronic Kidney disease are associated in the population.
