Single variable estimation models provide a means to estimate the desired characteristics of aproblem, using some previously estimated basic (independent) characteristic of the softwareproductsuch asits size.A single variable estimation modeltakes the followingform: d EstimatedParameter =c *e 1 1 154 Software Engineering Keerthana P, Manasa KN, Ganga D Bengal
