In statistics, ordinary least squares ( OLS) is a type of linear least squares method for estimating the unknown parameters in a linear regression model. The regression slope coefficient is (in simple linear regression) the correlation coefficient scaled by the variance of the $x$ and $y$ data.You might be interested: Readers ask: When did pizza come to america? Why is OLS unbiased?
There is a certain symmetry in the situation. Lm(formula = suva ~ heather, data = as.ame(data))
EXCEL LINEAR REGRESSION ESTIMATE CODE
See in the following code where R can get to both cases: lm(suva ~ heather, data = as.ame(data)) and in your Excel case the coefficient relates to 'heather'.in your R case the coefficient relates to 'suva'.The difference between coefficients is in the relation x versus y which is reversed in the one case. Why are they different in terms of their coefficients? Which one is correct?

Asking a separate question because whilst this has been answered for polynomial regression the solution doesn't work for me.
