Fitting a Linear Model to Survey Data When the Long-term Average Daily Intake of a Dietary Component Is an Explanatory Variable
نویسندگان
چکیده
The quest to improve dietary intake assessment and to achieve more accurate estimates of average daily consumption is ongoing. The primary dietary assessment method used in the National Health and Nutrition Examination Survey, conducted by the United States Center for Disease Control and Prevention, is the 24-hour recall of dietary intake (Moshfegh et al., 2008). Unfortunately, although this method is considered by many to provide the most accurate estimates for individual days, one day of intake is not representative of an individual’s longer-term or “usual” diet because of day-to-day variability.

Spatial Regression in the Presence of Misaligned data
In this paper, four approaches are presented to the problem of fitting a linear regression model in the presence of spatially misaligned data. These approaches are plug-in method, simulation, regression calibration and maximum likelihood. In the first two approaches, with modeling the correlation between the explanatory variable, prediction of explanatory variable is determined at sites...

The objective of this study was to develop a forecast model to determine the rate of generation of municipal solid waste in the municipalities of the Cuenca del Cañón del Sumidero, Chiapas, Mexico. Multiple linear regression was used with social and demographic explanatory variables. The compiled database consisted of 9 variables with 118 specific data per variable, which were analyzed using a ...
متن کاملA Generalized Linear Statistical Model Approach to Monitor Profiles
Statistical process control methods for monitoring processes with univariate ormultivariate measurements are used widely when the quality variables fit to known probabilitydistributions. Some processes, however, are better characterized by a profile or a function of qualityvariables. For each profile, it is assumed that a collection of data on the response variable along withthe values of the c...

The Daniel Fast is a biblically inspired dietary program rich in carbohydrate, most closely resembling a vegan diet but with additional restrictions, including the elimination of processed foods, white flour products, preservatives, additives, sweeteners, caffeine, and alcohol. While no specific requirements are placed on the ingestion of specific percentages of macronutrients, the mean daily c...
متن کاملShort Term Load Forecasting Using Empirical Mode Decomposition, Wavelet Transform and Support Vector Regression
The Short-term forecasting of electric load plays an important role in designing and operation of power systems. Due to the nature of the short-term electric load time series (nonlinear, non-constant, and non-seasonal), accurate prediction of the load is very challenging. In this article, a method for short-term daily and hourly load forecasting is proposed. In this method, in the first step, t...
