The two-parameter gamma distribution can be generalized by introducing a third parameter y, called a threshold or location parameter: replace x in (4.8), x 20 f(x; a) = r(a) (4.7) otherwise by x – y and x 2 0 by x 2 y. This amounts to shifting the density curves in the figure below so that they begin their ascent or descent at y rather than o. f(x; a, ß) 4 1.0- f(x; a.) + a = 2, ß = { 1.0 - a = 1 , a = 1, ß = 1 0.5- ‚a = .6 ,a = 2, ß = 2 0.5 - a = 2 ‚a = 5 a = 2, ß = 1 5 6 7 4

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
