      In general, since the CPU first looks to RAM for the data and instructions it needs, and since accessing RAM is faster than accessing secondary storage (e.g., a hard drive), more RAM means more conveniently stored, quickly accessed data and instruction. This means that the computer (CPU) will seem faster to the user with more RAM to keep more ...

      Although negative first order serial correlation is far less likely, the statistic d can be used to test for the existence of negative serial correlation as well. For this test the critical limits are 4 - DL and 4 - DU. The test then is: Ho (no serial correlation)

      The F statistic for joint significance of gyt 1 and i3t 1, obtained using the Stata “test” command, is 1.95, with p-value .16. Therefore, gyt 1 and i3t 1 are not jointly significant at even the 15% level. C11.9 (i) The first order autocorrelation for prcfat is .709, which is high but not necessarily a cause for concern.

      A test statistic is calculated. A common test statistic is a t-value. In this case, we are testing the value of one population mean, and the t-value (or sometimes used - a z value) is a measure of “how far” the sample mean is from the population mean that is specified in the null hypothesis.

      Now we can derive the pdf of the first order statistic for a random sample from the given exponential family. First, the population cdf is: F x = 0 x 1 θ exp - u θ du= -exp - u θ 0 x =1-exp - x θ . Now plugging in the population pdf and cdf we have: f X 1 x =n 1 θ exp - x θ exp - x θ n-1 = n θ exp - nx θ , when . θ >0 and x >0 .

      Loosely speaking, -1.18 is the smallest value you would expect to get if you took a sample of size 5 from a standard normal (i.e., the expected value of the first order statistic), and -0.50 is the second smallest value you would expect to get (i.e., the expected value of the second order statistic), and so on.
