Type I error definition

Type I error means the error made when it is concluded that an area of a site is below cleanup levels when it actually exceeds cleanup levels. This is the rejection of a true null hypothesis.

Type I error. Deciding favoritism exists when there is, in fact, no favoritism. TYPE II ERROR: Deciding parity exists when there is, in fact, favoritism. The probabilities of each type of each are: TYPE I ERROR: [OBJECT OMITTED]. TYPE II ERROR: [OBJECT OMITTED]. We want a balancing critical value, cB, so that (alpha) = (beta). It can be shown that. [OBJECT OMITTED]. where [OBJECT OMITTED] [OBJECT OMITTED] (PHI)() is the cumulative standard normal distribution function, and (phi)() is the standard normal density function. This formula assumes that Zj is approximately normally distributed within cell j. When the cell sample sizes, n1j and n2j, are small this may not be true. It is possible to determine the cell mean and variance under the null hypothesis when the cell sample sizes are small. It is much more difficult to determine these values under the alternative hypothesis. Since the cell weight, Wj will also be small (see calculate weights section above) for a cell with small volume, the cell mean and variance will not contribute much to the weighted sum. Therefore, the above formula provides a reasonable approximation to the balancing critical value. The values of mj and sej will depend on the type of performance measure. Mean Measure For mean measures, one is concerned with two parameters in each cell, namely, the mean and variance. A possible lack of parity may be due to a difference in cell means, and/or a difference in cell variances. One possible set of hypotheses that capture this notion, and take into account the assumption that transaction are identically distributed within cells is: H0: (mu)1j = (mu)2j, (sigma)1j2 = (sigma)2j2
