2003) have shown that the estimated

standard errors produced by S-Plus can systematically underestimate the true variability of fitted linear parameters in semiparametric GAMs.

For the new data on union and nonunion workers presented here,

standard errors for each estimate were computed.

0481) Notes: Figuren in parenthesis are

standard errors which have been indirectly estimated from the variance-covariance matrix.

linear regression, logistic regression, and analysis of variance) do not properly account for the nested structure of such data, and can yield biased parameter estimates, and incorrect

standard errors (Bryk & Raudenbush, 2001).

In the second phase, parameter estimations and

standard errors are obtained from m completed data sets.

Third, a fixed cut-off score would ignore the fact that different IQ tests have different

standard errors of measurement (SEM).

In the table, values in the column titled 'mean' are the averaged estimates of each parameter over 1000 Monte Caro replications; the 'asymptotic

standard error' is the model-based

standard error; the 'empirical

standard error' is the

standard errors of the 1000 estimates of each parameter; and the 'type I error' is the percent of times the null hypothesis--that the estimated parameter is equal to the true parameter--is rejected.

2009) demonstrated how neglecting to incorporate complex sample design information results in substantially smaller

standard errors and an increased risk of Type I errors.

In this issue, Siu and Morash do not use standard deviations at all, but instead use

standard errors (sometimes called

standard error of the mean).

The

standard errors for monthly natural gas volume and price estimates by State are given in Table C1.

We can estimate how much bigger by weighing the potential size of the October sample against typical sample sizes, historical

standard errors, and the likely inflation rate.

In the pooling phase, the patient disability estimates and

standard errors were combined into a single set of results for each of the three data sets (Figure 1).
