linreg-class: A Reference Class for linear regression
In amemem/lab4package: Linear Regression

This linear regression reference class will compute the coefficients, residuals, predicted values, standard errors for both the coefficients and the residuals, t-values and p-values, and the degrees of freedom of a model matrix based on the provided formula and data set.

formula: A formula object
data: A data set

coef(): Returns the coefficients.
initialize(formula, data): The constructor will return an object of class linreg.
plot(): Plots two graphs; residuals vs fitted values, and scale-location.
pred(): Returns the predicted values.
print(): Prints how the function was called and the coefficients.
resid(): Returns the residuals.
summary(): Prints a summary of the model.
