Hi, I have a linear equation P = a + bM + c(Y-1) + d(M(Y-1)) where a, b, c and d are coefficients (constants). P, Y and M are known properties. Specifically, there are multiple P values, each with their corresponding Y and M values. How do I use matlab or excel to fit the data to the equation above to obatin the a, b, c & d coefficients? Please see image below. So each P value has 2 Y values and 2 M values. Any ideas?Hi, I have a linear equation P = a + bM + c(Y-1) + d(M(Y-1)) where a, b, c and d are coefficients (constants).
