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 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...

Finally, I’ve been experimenting a bit with using the input in a formula interface, more similar to the way ggplot in R allows you to do this. So this is a new function,plot_form, and here is an example Poisson linear model:
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...
linear association, whereas data pairs(Xi,Yi)(X_i, Y_i)(Xi,Yi)that are tightly clustered around a straight line have a strong linear association. Being able to quickly assess the linear association between two variables is one of the main purposes of using a scatter plot generator....
Use Scatterplot to make enhanced scatterplots, with options to include boxplots in the margins, a linear regression line, a smooth curve via non-parametric regression, a smoothed conditional spread, outlier identification, and a regression line. ...
