Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models where the dependent variable is dichotomous.

Logistic regression is a fundamental classification technique. It belongs to the group of linear classifiers and is somewhat similar to polynomial and linear 

The discussion of logistic regression in … Logistic regression is a predictive modelling algorithm that is used when the Y variable is binary categorical. That is, it can take only two values like 1 or 0. The goal is to determine a mathematical equation that can be used to predict the probability of event 1.

Logistic regression

Logistic regression is a supervised learning classification algorithm used to predict the probability of a target variable. The nature of target or dependent variable is dichotomous, which means there would be only two possible classes.

Unlike linear regression which outputs continuous number values, logistic regression transforms its output using the logistic sigmoid function to return a probability value which can then be mapped to two or more discrete classes. Logistisk regression är en matematisk metod med vilken man kan analysera mätdata. Metoden lämpar sig bäst då man är intresserad av att undersöka om det finns ett samband mellan en responsvariabel (Y), som endast kan anta två möjliga värden, och en förklarande variabel (X). Indeed, logistic regression is one of the most important analytic tools in the social and natural sciences.

Logistic regression is a simple and more efficient method for binary and linear classification problems. It is a classification model, which is very easy to realize and achieves very good performance with linearly separable classes. Using logistic regression to predict class probabilities is a modeling choice, just like it’s a modeling choice to predict quantitative variables with linear regression. 1 Unless you’ve taken statistical mechanics, in which case you recognize that this is the Boltzmann Logistic regression is used to describe data and to explain the relationship between one dependent binary variable and one or more nominal, ordinal, interval or ratio-level independent variables. Sometimes logistic regressions are difficult to interpret; the Intellectus Statistics tool easily allows you to conduct the analysis, then in plain Medium Logistic regression is a technique for predicting a dichotomous outcome variable from 1+ predictors. Example: how likely are people to die before 2020, given their age in 2015? Note that “die” is a dichotomous variable because it has only 2 possible outcomes (yes or no).
