Description We are studying discrete mathematics this semester. discrete mathematics can be called computer mathematics. It is a basic course for many computer professional courses in the future. Now we try to use computer programming to solve the problem of discrete mathematics. We can both review discrete mathematics and carry out programming practices, which is the best of both worlds. Task Compile the program to determine whether a proposition

squares and minimums of residuals, the formula for residuals and the sum of squares of residuals are as follows:The above formula is derived in the way of the sum of squares of the minimum residuals, and there is a way of thinking that the same formula can be deduced with the maximum likelihood, first of all the assumptions about the model: The error eq
