I'm trying to add the equation for a linear regression line to a scatter plot that I have made. I first plotted my data points then used the polyfit function to add a first-order line to my plot. Now I want the equation of the line in y = mx + b form to...

A regression equation is calculated and the associated trend line is plotted on scatter plots. The trend line models the relationship between the two variables, with both linear (Linear) and nonlinear (Exponential,Logarithmic,Power, andPolynomial) trend line options available. The R² value quant...

A nice way to add info and highlight trend in a scatter plot is to add aregression lineon top of the dots. Thanks to itsregplot()andlmplot()function, it's quite easy! The main difference between those 2 functions are that: regplot()is used for simple scatter plot with a trend line...

In our first scatterplot with regression lines, some curves deviate substantially from linearity as shown below.Sadly, this chart's legend doesn't quite help to identify which curve visualizes which transformation function. So let's look at the regression table shown below....
