Using the EM Algorithm to Estimate the Difference in Dependent Proportions in a 2 x 2 Table with Missing Data.
… between correlated proportions. To obtain the standard error of this difference I employ a resampling technique known as bootstrapping. The performance of the bootstrap standard error is evaluated for different sample sizes and different fractions of missing information. Finally, a 100(1-α)% …

Statistical Analysis Of Diffusion Bonding Nickel Using Brass Interlayers
… proved to provide a good model with a fairly low standard error that can accurately predict the composition of the system across the diffusion bond area. The strength model provided two significant terms, and had a very high standard error. This meant that the model was not very good at predicting …

Channel coding for high speed links
… to support data rates in the Gbps range at low error probabilities. Modeling the high-speed link as a communication system with noise and intersymbol interference (ISI), this work identifies three operating regimes based on the underlying dominant error mechanisms. The resulting framework is …

Predicting New Jersey High School Proficiency Test Results in Mathematics and Language Arts Using Community Demographic Data
… to influence student achievement on high-stakes standardized assessments. School level data included percentage of families in poverty for 12 months, percentage of lone-parent households (total), and percentage of population with some college. Final analysis utilized hierarchical linear …

A denoising algorithm for surface EMG decomposition
… on the level of denoising (p’s <0.05). The error-filtered estimation (EFE) algorithm was used to calculate the inter-discharge interval (IDI) for the denoised MUPTs. In total, VR decreased 24.88% and the SNR increased 6.0% (p’s < 0.05). The standard error of estimate (3.2 versus 3.69%) in …

Predicting the level of cognitive function from standing balance and salivary biomarkers
… correlation coefficients [ICC]) and absolute (standard error [SEM]) reliability of anteroposterior (AP) and mediolateral (ML) centre of pressure (COP) path lengths were determined in each condition and foot position. The acceptability of each foot position and the MoCA was assessed using a …

Temporal variation in infection of male sardine (Sardinops sagax) by a coccidian testicular parasite (Eimeria sardinae)
… the southern stock. Mean infection intensity and standard error of the western stock was 6.7±0.7 and for the southern stock was 8.3±1.0. Parasite abundance and standard error of the western stock was 5.3±0.2 and 6.1±0.3 for the southern stock. A significant difference was observed within testes …

Mistaking the Forest for the Trees: The Mistreatment of Group-level Treatments in the Study of American Politics
… one can never be sure that the unobserved (or error) component of the data generating process conforms to the assumptions one must make to use the model. If it does not, then this manifests itself in terms of bias in standard errors and incorrect inference on statistical significance of …

Spatial factors affecting white grub presence and abundance in golf course turf
… between actual and predicted values was -0.15, standard deviation = 0.79, R2 = 81.38%. Additionally, a study was conducted to determine whether the number of white grubs collected from transects of sampled golf course fairways was significantly different from those found in the roughs. White …

Least squares estimation for latent variables with dichotomous item response data
… simulation study suggested that the empirical standard error of LSE is less than the asymptotic standard error of JMLE, and the empirical bias of LSE is less than those of JMLE and Bayesian estimators. The result of the second simulation study suggested that the accuracy of LSE and its …

An evaluation of parameter estimation when using multilevel structural equation modeling for mediation analysis
… estimation of indirect effect parameters and standard errors based on the conventional multilevel model (MMM) has been assessed, this is not the case for the use of the MLSEM model for estimating indirect effects. This simulation study was designed to investigate the use of the MLSEM for …

Optimizing peak gust and maximum sustained wind speed estimates from mid-latitude wave cyclones
… over short distances and thus the highest error measurements associated with concurrent interpolated surfaces. For this reason, various covariates were utilized in conjunction with the cokriging interpolation technique and improved the interpolated wind surfaces for five wind storms that …
