However, when I have the data plotted in a log-log scaled graph (both axes in logarithmic scale) the linear fit does not appear to me to be linear. How can I perform a linear regression in a log-log graph with Matlab. I have attached a picture of the graph and the linear fitting that I obtained. Any help is much appreciated! Thank you in advance!

Each row of the input data represents one observation. Compute the regression coefficients for a linear model with an interaction term. X = [ones(size(x1)) x1 x2 x1.*x2]; b = regress(y,X) % Removes NaN data b = 4×1 60.7104 -0.0102 -0.1882 0.0000 LinearModel is a fitted linear regression model object. A regression model describes the relationship between a response and predictors. The linearity in a linear regression model refers to the linearity of the predictor coefficients.

In MATLAB, you can find using the mldivide operator as B = X\Y. From the dataset accidents, load accident data in y and state population data in x. Find the linear regression relation between the accidents in a state and the population of a state using the \ operator. The \ operator performs a least-squares regression.

This display gives some of the basic information to check whether the fitted model represents the data adequately.

Is that possible in MatLab? I need the slope, intercept and R-squared. In fitlm, mdl = Linear regression model: y ~ 1 + x1 + x2 + x3 Does it mean it is fitted as y = 1 + x1 + x2 + x3?
