![]() Note that in addition to the linear equation, it also returns the R2 score, which can be useful. The simplest solution I found for the question at hand can be found in the following post: ![]() If I had some set of scatter points in an array var points = .], I would be able to hand that to some function like lin_reg(points) and it would return something like if the linear equation was y = 7.12 x + 3. R21sum squared regression (SSR)total sum of squares (SST). The hope would be that I could use the library like so. In the context of regression it is a statistical measure of how well the regression line. I stumbled upon jStat, but it is completely missing documentation (as far as I can find) and after digging through the the source code it doesn't seem to have any linear regression functionality built in-I'm basing this purely on function names however.ĭoes anyone know any Javascript libraries that offer simple regression analysis? Linear regression is probably the most popular form of regression analysis because of its ease-of-use in predicting and forecasting. I can't seem to find any libraries that will help me to do this though. Regression in machine learning consists of mathematical methods that allow data scientists to predict a continuous outcome (y) based on the value of one or more predictor variables (x). I imagine I would calculate the linear, polynomial, exponential and logarithmic equations and then choose the one with the highest R^2 value. We can create our project where we input the X and Y values, it draws a graph with those points, and applies the linear regression formula. I want to do Least Squares Fitting in Javascript in a web browser.Ĭurrently users enter data point information using HTML text inputs and then I grab that data with jQuery and graph it with Flot.Īfter the user had entered in their data points I would like to present them with a "line of best fit".
