Regression analysis (Multiple Regression Analysis) is multiples to study the relationship between the independent variable or variables that serve as a prophecy of two or more variables by 1 in the regression analysis, multiples, it must find a correlation coefficient value multiples (Multiple Correlati.On Coefficient) to determine the relationship between the independent variable or variables with variables such as whether there is any correlation for regression analysis, multiples. Will need to find the equation for the regression to the prediction of variable (Y), and standard error, as well as the correlation value multiples (Multiple Correlation) to find a linear relationship that is possible between independent variables or maximum variables beginning with variable?สมมติให้ข้อมูลประกอบด้วยตัวแปรอิสระ k ตัว จะได้สมการแสดงความสัมพันธ์ของค่าเฉลี่ยและตัวแปรอิสระทั้งหมด เป็นดังนี้
