Suppose that we want to model the above set of data with a linear model y = ax + b. Since
our model may be perfect and there might be some noise in the measurements y, we assume
y = ax + b + e, where e is the error in our modeling.
a) Write down the matrix structure for this problem using the given model and the input-
out data.
b) Write down the structure of the solution for the coefficients a and b. You are not
required to solve for the unknown parameters in our model but rather the form of the
solution using least-squares error method.
c) Suppose that the least squares solution for the unknown parameters are a =
0.0691
and b = -0.4761, resulting in ŷ = 0.0691 x – 0.4761. Using this model and the
given input-output data, find the squared-error defined as follows
e? = E-1(Vn - Pn)?, where y, is the nth measurement and ŷ, is the output of the
model evaluated at the nth input data.
