Building, evaluating, and using the resulting model for inference, prediction, or both requires many considerations. This paper, written for experienced users of SAS statistical procedures, illustrates the nuances of the process with two examples: This paper describes SAS Viya procedures for building linear and logistic regression models, generalized linear models, quantile regression models, generalized additive models, and proportional hazards regression models.
In addition, variance estimation by the bootstrap method is available in the survey data analysis procedures, and the PHREG procedure provides cause-specific proportional hazards analysis for competing-risk data. Several other procedures have been enhanced as well. This paper shows how you can use PROC MCMC to fit hierarchical models that have varying degrees of complexity, from frequently encountered conditional independent models to more involved cases of modeling intricate interdependence.
This paper reviews the statistical methods that are implemented in the CAUSALTRT procedure and includes examples of how you can use this procedure to estimate causal effects from observational data.
This paper uses an example to illustrate the new functionality. This paper describes how to use the MCMC procedure to fit Bayesian mixed models and compares the Bayesian approach to how the classical models would be fit with the familiar mixed modeling procedures.
This paper provides recommendations for circumventing memory problems and reducing execution times for your mixed-modeling analyses.
Lastly, it focuses on the best way to interpret and address common notes, warnings, and error messages that can occur with the estimation of mixed models in SAS software. This paper introduces the principles of Bayesian inference and reviews the steps in a Bayesian analysis. Then it explains how to perform model selection by applying these techniques with the GLMSELECT procedure, which includes extensive customization options and powerful graphs for steering statistical model selection.
This paper discusses two commonly used regression approaches for evaluating the relationship of the covariates to the cause-specific failure in competing-risks data. One approach models the cause-specific hazard, and the other models the cumulative incidence. Marginal model plots enable you to evaluate model fit by comparing predicted values given all of the variables in the full model and a loess fit function for each independent variable.
When the two functions are similar in each of the graphs, there is evidence that the model fits well. When the two functions differ in at least one of the graphs, there is evidence that the model does not fit well.
This paper illustrates how you can create and use path diagrams to present your model and statistical results. Examples are included to illustrate the flexibility that PROC GLIMMIX offers for modeling within-unit correlation, disentangling explanatory variables at different levels, and handling unbalanced data. This paper demonstrates the new case-level residuals in the CALIS procedure and how they differ from classic residuals in structural equation modeling SEM. This paper highlights how measures of nonlinearity help you diagnose models and decide on potential reparameterization.
This paper describes a variety of IRT models, such as the Rasch model, two-parameter model, and graded response model, and demonstrates their application by using real-data examples. Finally, the paper explains how the application of IRT models can help improve test scoring and develop better tests. This paper reviews the definition of LS-means, focusing on their interpretation as predicted population marginal means, and it illustrates their broad range of use with numerous examples.

The global production of paper and cardboard stood at approximately million metric tons in More than half of that production was attributable to packaging paper, while almost one third was attributable to graphic paper.
The world's three largest paper producing countries are China, the United States, and Japan. In , International Paper generated more than 21 billion U. China is the world's largest paper and paperboard consumer in the world, using more than million metric tons annually, followed by the U. Since paper can be classified as a renewable resource, recovery is crucial within the paper industry. Paper, among many materials, has one of the highest recycling rates.
In , around million metric tons of recovered paper was collected worldwide. In the United States, more than 52 million short tons of paper and paperboard are recovered annually.
The paper and paperboard recovery rate in the U. This text provides general information. Statista assumes no liability for the information given being complete or correct. Due to varying update cycles, statistics can display more up-to-date data than referenced in the text.
Production of paper and cardboard worldwide. This section should translate the intellectual concerns expressed above into your research. Indicate here the nature and source of your data i. For example, do you expect the hypothesized relationship to hold across sex and race for individual-level data or across types of political systems for national-level data?
You must also formalize your hypotheses in this section. By formalize, I mean physically distinguish your hypotheses from the rest of the text in two ways: For example, you might say, "This leads to our first hypothesis: Hypotheses should be bold assertions of expectations that lend themselves to falsification. They gain in credibility as they survive attempts to test them -- i. Admittedly, it is intellectually more satisfying to propose hypotheses that are supported rather than falsified through data analysis.
Whether your hypotheses are supported or falsified will have no effect on the paper's grade. Whenever possible, formulate directional hypotheses, which invite falsification more readily than non-directional hypotheses. We will discuss the difference between the two soon. Also pay attention to the linkage between the concepts in your theory and in the way you operationalize those concepts in formulating your hypotheses.
Be careful not to throw away data by collapsing variables to do crosstabulations when they might more properly be analyzed instead through correlational and regression analysis. For example, the "thermometer" variables in the VOTE88 data are expressed from 0 to , while those in VOTE96 are collapsed into a few ordinal categories.
Report here the results of your statistical tests. Refer explicitly to the hypotheses being tested by number: H1, H2, and so on. In most cases, your data should report tabulations of statistics. If you use ordinal or continuous data, your statistics will involve correlation coefficients, regression coefficients, or results of t-tests or F-tests. Do not simply accept and report the format of SPSS computer printout. That's not very classy.
Instead, reformat the data into tables like those in the Journal of Politics or someother professional journal. Take some care in reporting your tables. Be sure to include the Ns on which any percentages are based. We will deduct points if Ns are not included. Statistical tables should contain all the information that the reader needs to analyze the test.
Your job as writer is to point out the key features of the analysis, not to repeat all the numbers in the tables. The data are in the table; the text should be used to summarize its particulars. Please report correlations and slopes if you employ regression analysis only to the second decimal point.
Do not slavishly reproduce them to the ultimate decimal point from the SPSS output.
