다중 선형 회귀

다중 예측 변수를 사용하는 선형 회귀

저차원에서 중간 차원까지의 데이터 세트에 대한 정확도를 높이려면 fitlm을 사용하여 선형 회귀 모델을 피팅하십시오.

고차원 데이터 세트에 대한 계산 시간을 단축하려면 fitrlinear를 사용하여 선형 회귀 모델을 피팅하십시오.

선형 회귀 소개

What Is a Linear Regression Model?

Regression models describe the relationship between a dependent variable and one or more independent variables.

선형 회귀

선형 회귀 모델을 피팅하고 결과를 검토합니다.

Stepwise Regression

In stepwise regression, predictors are automatically added to or trimmed from a model.

Reduce Outlier Effects Using Robust Regression

Fit a robust model that is less sensitive than ordinary least squares to large changes in small parts of the data.

Choose a Regression Function

Choose a regression function depending on the type of regression problem, and update legacy code using new fitting functions.

Summary of Output and Diagnostic Statistics

Evaluate a fitted model by using model properties and object functions.

Wilkinson Notation

Wilkinson notation provides a way to describe regression and repeated measures models without specifying coefficient values.

Linear Regression Workflow

Import and prepare data, fit a linear regression model, test and improve its quality, and share the model.

선형 회귀 결과 해석하기

선형 회귀 결과 출력되는 통계량을 표시하고 해석합니다.

Linear Regression with Interaction Effects

Construct and analyze a linear regression model with interaction effects and interpret the results.

Linear Regression Using Tables

This example shows how to perform linear and stepwise regression analyses using tables.

Linear Regression with Categorical Covariates

Perform a regression with categorical covariates using categorical arrays and fitlm.

Analyze Time Series Data

This example shows how to visualize and analyze time series data using a timeseries object and the regress function.

Train Linear Regression Model

Train a linear regression model using fitlm to analyze in-memory data and out-of-memory data.

부분 최소제곱 회귀

Partial Least Squares

Partial least squares (PLS) constructs new predictor variables as linear combinations of the original predictor variables, while considering the observed response values, leading to a parsimonious model with reliable predictive power.

부분 최소제곱 회귀 및 주성분 회귀

이 예제에서는 부분 최소제곱 회귀(PLSR) 및 주성분 회귀(PCR)를 적용하는 방법을 보여주고 이 두 방법의 효과를 설명합니다.
