1. Simple linear regression. Start by creating a wave with a known slope and additive Gaussian noise. Make/O/N=100 data1=x+gnoise(4) The simple linear regression analysis is obtained by: StatsLinearRegression /T=1/Q data1 The results appear in the Linear Regression table (shown transposed...
First, we need to create some example data that we can use in our linear regression:set.seed(2580) # Create random example data N <- 1000 x <- sample(1:5, N, replace = TRUE) y <- round(x + rnorm(N), 2) x <- as.factor(x) data <- data.frame(x, y) head(data) # x ...
Multiple linear regression (MLR) is a statistical technique that uses several explanatory variables to predict the outcome of a response variable.
