I have some multiple linear models without intercept like below:
Y = a*X1 + b*X2 + c*X3
However this model is a linear model, but since it does not have an intercept we have to write it as a non-linear model in R:
model1= nls(Y ~ a*X1+b*X2, data = trainDat, start = list(a = 1, b=1))
The problem is that the summary(model1) does not give us the statistics of the model like F-statistics because it is not lm.
How can we report the significance of these models in R?
