WebHi, I am looking for a statistician to look over existing 2 R script files to check the work and the output, which I think need some fine-tuning. The project is using supervised machine learning via a binary logistic regression model to assess probability of death and poor functional outcome in a group of patients. I have trained a new set of regression models … WebJun 9, 2024 · Logistic regression work with odds rather than proportions. The odds are simply calculated as a ratio of proportions of two possible outcomes. Let p be the proportion of one outcome, then 1-p will be the proportion of the second outcome. Mathematically, Odds = p/1-p The statistical model for logistic regression is log (p/1-p) = β0 + β1x
WebRegression What you probably need is a Logistic Regression model. A regular linear regression model needs a continuous dependent variable to work, but a logistic regression is used to predict a binary outcome variable.
