Logistic regression output in r

WitrynaFor Linear Regression, where the output is a linear combination of input feature (s), we write the equation as: `Y = βo + β1X + ∈` In Logistic Regression, we use the same equation but with some modifications made to Y. Let's reiterate a fact about Logistic Regression: we calculate probabilities. And, probabilities always lie between 0 and 1. WitrynaMany aspects of the logistic regression output are similar to those discussed for linear regression. For example, we can use the estimated standard errors to get confidence intervals as we did for linear regression in Chapter 4:
