Here, x, u and y represent the states, inputs and outputs respectively, while A, B, C and D are the state-space matrices. The ss object represents a state-space model in MATLAB ® storing A, B, C and D along with other information such as sample time, names and delays specific to the inputs and outputs.

Increasing the relative precision to 90%, reduces the sample size to 14 in each group, whilst decreasing the prevalance for customers over 25 to 1% increases the sample size to 637 per group. Formula. This calculator uses the following formula for the sample size, n a, for the absence group: n a = [Z α/2 2 / log 2 (1-RP)] * [1/X + 1/Y] where,
