Hi, I've made a model and it's predicting prices of cars. hooray! I cannot find the the equation for Azure's Regression Linear model anywhere. I made this model using Designer GUI. For example, in R, the coefficients are returned by running summary(mymodel)
= y-intercept + (slope * miles) + (slope * year)
= 21022.96 + (-0.0249*98500) + (-6.5668*2016)
something like this equation for a line is what I'm looking for in Azure.

what I've tried:

  1. If it was only 1 feature, I could solve for an equation using (y2-y1) / (miles2-miles1) to find slope and the solve to y intercept. But this model uses miles and year as variables.

    @@MikeRichardson-3493 Thanks, We currently do not have coefficients for regression models, but we will forward this with our data science team to check on this. We are working on an interface to surface models that compose ensembles, model weights and more. While not as involved of an interface, some of this information is available today within the model details tags sections:.

    ok, thanks. If I understand correctly, I could make this model an ensemble model containing two algorithms, that each use one factor/feature variable, and then this would allow me to add weights at each model. And the calculation of the equation can be made if it's linear regression on one feature. I will look forward to trying this. Thanks for the insight.
