Q7. What are the two required statements while using PROC CATMOD?

The PROC CATMOD and MODEL statements are required.

Q8. What is the PROC GLM procedure in SAS/STAT and what is its syntax?

The PROC GLM suits linear models the usage of the approach of least squares. SAS PROC GLM handles models through touching on one or numerous continuous established variables to one or numerous independent variables. It has statistical methods like regression, evaluation of variance, evaluation of covariance, multivariate evaluation of variance, and partial correlation.

PROC GLM dataset;
CLASS variables;

Q9. Which procedure in SAS STAT can be used for analysis of variance on random effects for data?

PROC NESTED can be used for this type of data. The PROC NESTED procedure in SAS/STAT performs analysis of variance on random outcomes for data from an experiment that has a nested (hierarchical) shape. SAS PROC NESTED is suitable for models with only class effects, it does no longer deal with fashions that include continuous covariates.

Q10. What is Bayesian analysis?

SAS/ STAT Bayesian Evaluation is a statistical technique that helps us in answering research questions on unknown parameters the usage of chance statements.

Q12. How can we fit statistical models in SAS STAT?

The PROC FMM system in SAS/STAT software suits statistical models to statistics for which the distribution of the response is a finite combination of distributions—that is, each reaction is drawn with an unknown opportunity from certainly one of several distributions.

Q13. What does the OUTPOST= option in the GENMOD procedure do?

The outpost = option saves samples (posterior) to the POST dataset for post-processing.

Q14. What is the syntax for the PROC MCMC procedure?

PROC MCMC dataset;
PARMS <list of parameters>;
PRIOR <type of distribution of each parameter>;
MODEL <variable used as likelihood>;

Q15. What is the PROC LOGISTIC procedure used for in SAS STAT and what are the required statements in it?

The PROC LOGISTIC process in SAS/STAT plays a logistic regression of statistics. The LOGISTIC technique suits linear logistic regression models by way of the method of maximum probability.

The PROC LOGISTIC and model statements are required statements.

Q16. Explain the use of each statement in the below syntax.

PROC PROBIT dataset;
CLASS <dependent variables>;
Model< dependent variables>= <independent VARIABLES>;

The DATA= option specifies the dataset that will be studied.

The PLOTS= choice within the PROC PROBIT statement, collectively with the ODS graphics announcement, requests all plots (due to the fact all has been specified in brackets, we will pick out a selected plot also) for the anticipated opportunity values and peak ranges.

The model statement prepares a response between a structured variable and impartial variables. The variables top and weight are the stimuli or explanatory variables.

The new dataset is created by OUTPUT statement. For example, ABC, that contains all the variables of the original data set, and a new variable, PROB that represents possibilities.

Q17. What are the different plot options that can be specified with the PLOT= option in the PROC PROBIT procedure?

The different plot options that can be specified with PLOTS= option are-
