In statistics, linear regression is a linear method to model the relationship between a scalar response (dependent variable), y , and one or more explanatory variables (independent variables), x , a vector. When there is only one explanatory variable, it is called simple linear regression. ...
where N is the number of observations used to fit the model, Σ is the summation symbol, xi is the x value for observation i, x is the mean x value, yi is the y value for observation i, y is the mean y value, σx is the standard deviation of x, and σy is the standard ...

The lm function in R can be used to fit a linear regression. model <- lm(PEFR ~ Exposure, data=lung) lm stands for linear model and the ~ symbol denotes that PEFR is predicted by Exposure. Printing the model object produces the following output: Call: lm(formula = PEFR ~ Exposure, ...
The symbol r is used for the correlation coefficient for the data sample (and ρ for the population). The most popular one is the Pearson product moment correlation coefficient, defined as (8.23)r=n∑xiyi−∑xi∑yi[n∑xi2−(∑xi)2][n∑yi2−(∑yi)2]=ABA2B2. The range of r ...

Linear regression, in statistics, a process for determining a line that best represents the general trend of a data set. The simplest form of linear regression involves two variables: y being the dependent variable and x being the independent variable. T
