... The size of each population is large relative to the sample drawn from the population. That is, N 1 is large relative to n 1 , and N 2 is large relative to n 2 . (In this context, populations are considered to be large if they are at least 10 times bigger than their sample.) The samples are independ ...

xtreg and xtmixed: recap
... And this you can do with xtmixed xtmixed y x1 ||:
is just like the xtreg command, but if you want
random slopes for x1, you add x1 after the “:”
xtmixed y x1 || : x1
Your output then gives you estimates for the
variance (or standard deviation) of delta and zeta.

Chapter 9: Sampling Distributions
... a) np > 10 and b) n(1-p) > 10 There are no outliers or other important deviations from the main pattern The mean (center) of the distribution is equal to the true population parameter, p. The variability (spread) of the sampling distribution depends on the sample size. The larger the sample-size the ...

Use a 90% confidence interval to estimate the mean percent of nitrogen in ancient air. Follow the four-step process as illustrated in Example 18.2. (Our present-day atmosphere is abo ...

... 20. The same sample data is used to calculate 99%, 90% and 95% confidence interval of the true mean. Which of those intervals has the smallest bound on the error estimation? (a) 90% narrower interval has smaller bound on the error estimation (b) 95% (c) 99% (d) we do not have enough information to a ...
