In statistics, linear regression is a linear approach to modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression. Icke-linjär regression Icke-linjära modeller • Hittills: enkel / multipel linjär regression • Ofta är sambandet mer komplicerat i verkligheten • Icke-linjära samband – Polynomsamband – Exponentiella samband – Loglinjära samband • Vi behöver ha kunskap om sambandets form för att skatta icke-linjära modeller
This tutorial explains how to perform simple linear regression in SPSS. Example: Simple Linear Regression in SPSS.

Simple linear regression is a technique that predicts a metric variable from a linear relation with another metric variable. Remember that “ metric variables ” refers to variables measured at interval or ratio level. The point here is that calculations -like addition and subtraction- are 2017-10-11 Simple linear regression was carried out to investigate the relationship between gestational age at birth (weeks) and birth weight (lbs). The scatterplot showed that there was a strong positive linear relationship between the two, which was confirmed with a Pearson’s correlation coefficient of 0.706.
