Calculating OLS Coefficients
You are tasked with fitting a simple linear model. Given the design matrix X (which includes a column of ones for the intercept) and the target vector y, calculate the coefficient vector β̂ using the equation β̂ = (XᵀX)⁻¹Xᵀy.
X = [[1, 1], [1, 3], [1, 2]]
y = [3, 7, 5]
Provide the final coefficient vector β̂.

A data scientist is attempting to find the optimal coefficients () for a linear model using the equation , where is the matrix of input features and is the vector of target values. The calculation fails, returning a 'singular matrix' error. What is the most likely cause of this error in the dataset represented by matrix ?
