The data comes in a dictionary format, where the main data is stored in an array called data, and the target values are stored in an array called target. Abstract- In this paper we have used Logistic regression to the data set of size around 1200 patient data and achieved an accuracy of 89% to the problem of identifying whether the breast cancer tumor is cancerous or not using the logistic regression model in data analytics using python scripting language. Predicting Breast Cancer - Logistic Regression. In this series we will learn about real world implementation of Artificial Intelligence. The logistic function, also called the sigmoid function was developed by statisticians to describe properties of population growth in ecology, rising quickly and maxing out at the carrying capacity of the environment. It is a binomial regression which has a dependent variable with two possible outcomes like True/False, Pass/Fail, healthy/sick, dead/alive, and 0/1. The chance of getting breast cancer increases as women age. 0. even in case of perfect separation (e.g. The use of CDD as a supplement to the BI-RADS descriptors significantly improved the prediction of breast cancer using logistic LASSO regression.
