Is there a company that does linear regression in R?
His company, Sigma Statistics and Research Limited, provides both on-line instruction and face-to-face workshops on R, and coding services in R. David holds a doctorate in applied statistics. I’m reaching out on behalf of the University of California – Irvine’s Office of Access and Inclusion.
How to plot a regression line in R?
Seems you address a multiple regression problem (y = b1x1 + b2x2 + … + e). In this case, you obtain a regression-hyperplane rather than a regression line. For 2 predictors (x1 and x2) you could plot it, but not for more than 2. Nice!
What is the intercept and slope of your regression?
We see that the intercept is 98.0054 and the slope is 0.9528. By the way – lm stands for “linear model”. In the next blog post, we will look again at regression. See our full R Tutorial Series and other blog posts regarding R programming.
