As the number of subjects becomes large, the sampling distribution of the mean approaches normality and the mean clusters around the true population mean. Statistical inference is likely to work when the sample is large and representative of the entire population (if equal to that population, it ...
and the true characteristics of a population is referred to as sampling error, which is often expressed in terms of the standard error and bias of estimates. In statistical theory, the sampling errors will converge to zero as the sample size increases. Probability samples provide the basis for ...

Suppose, for example, that your model has an input port operating at one rate (with a sample time index of 0) and an output port operating at a slower rate (with a sample time index of 1). Further, suppose that you want the output port to output the value currently on the input. ...
