# Which of the following characterizes the difference between a linear and logistic regression?

## Which of the following characterizes the difference between a linear and logistic regression?

The essential difference between these two is that Logistic regression is used when the dependent variable is binary in nature. Linear regression is used when the dependent(output/outcome) variable is continuous. Whereas, Logistics regression is used when the dependent variable is categorical(binary).

## Which is more accurate linear or logistic regression?

The method for accuracy in linear regression is the least square estimation whereas for logistic regression it is maximum likelihood estimation. In Linear regression, the output should be continuous like price & age, whereas in Logistic regression the output must be categorical like either Yes / No or 0/1.

## Why are SVMS often more accurate than logistic regression?

SVM try to maximize the margin between the closest support vectors whereas logistic regression maximize the posterior class probability. For the kernel space, SVM is faster.

## What kind of outcomes does Logistic Regression predict?

Logistic regression is an extremely robust and flexible method for dichotomous classification prediction; that is, it is used to predict for a binary outcome or state, such as yes/no, success/failure, and will occur/won’t occur.

## Should I use linear or logistic regression?

Linear Regression is used to handle regression problems whereas Logistic regression is used to handle the classification problems. Linear regression provides a continuous output but Logistic regression provides discreet output.

## Why is the logistic regression is considered linear?

The short answer is: Logistic regression is considered a generalized linear model because the outcome always depends on the sum of the inputs and parameters. Or in other words, the output cannot depend on the product (or quotient, etc.) of its parameters!

## Why is SVM better than linear regression?

SVM tries to finds the “best” margin (distance between the line and the support vectors) that separates the classes and this reduces the risk of error on the data, while logistic regression does not, instead it can have different decision boundaries with different weights that are near the optimal point.

## What are the assumptions of logistic regression?

Basic assumptions that must be met for logistic regression include independence of errors, linearity in the logit for continuous variables, absence of multicollinearity, and lack of strongly influential outliers.

## When to use logistic regression for a dependent variable?

Logistic regression is used to predict the categorical dependent variable with the help of independent variables. The output of Logistic Regression problem can be only between the 0 and 1. Logistic regression can be used where the probabilities between two classes is required.

## Do you need a linear relationship in logistic regression?

In Logistic regression, it is not required to have the linear relationship between the dependent and independent variable. In linear regression, there may be collinearity between the independent variables.

## How is logistic regression used in machine learning?

Logistic regression is one of the most popular Machine learning algorithm that comes under Supervised Learning techniques. It can be used for Classification as well as for Regression problems, but mainly used for Classification problems.

## Can you run a linear regression on a higher order model?

You can still run a Linear Regression on a higher order model. A common misunderstanding is that only linear functions can be created with linear regression methods.
