Logistisk regressionsanalys - Statistikhjälpen

There are basically four reasons for this. 1. Logistic regression analysis is used to examine the association of (categorical or continuous) independent variable (s) with one dichotomous dependent variable. This is in contrast to linear regression analysis in which the dependent variable is a continuous variable. The discussion of logistic regression in this chapter is brief. 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.

Logistic regression is fast and relatively uncomplicated, and it’s convenient for you to interpret the results. Logistic regression is a powerful machine learning algorithm that utilizes a sigmoid function and works best on binary classification problems, although it can be used on multi-class classification problems through the “one vs. all” method.

The curve is restricted between 0 and 1, so it is easy to apply when y is binary.

It is similar to a linear regression model but is suited to models where the dependent variable is dichotomous. 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.

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). Logistic regression is a classification algorithm used to assign observations to a discrete set of 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).
