Regression coefficient

How it is used

Written b or B for unstandardised and β (beta) for standardised coefficients, and reported with its standard error, confidence interval and p-value. The sign shows the direction: a negative coefficient means the outcome tends to fall as the predictor rises.

Example sentences

1. With pay measured in thousands of lira, a regression coefficient of 1.2 for experience means each extra year goes with about 1,200 lira more per month.

2. Standardised regression coefficients let you compare predictors measured on different scales.

Related terms

• linear regressionA regression method that models the outcome as a straight-line function of one or more predictors, estimating an intercept and one slope per predictor.
• standard errorThe standard deviation of an estimate, such as a sample mean, across repeated samples; it shows how precise the estimate is likely to be.
• least squaresA method of fitting a line or model by choosing the parameter values that make the sum of the squared residuals as small as possible.
• multiple regressionA regression model with two or more predictor variables, used to estimate the effect of each one while holding the others constant.
