What does CLB in SAS mean?

The CLB option adds the upper and lower 95% confidence limits for the parameter estimates; the. level can be changed by specifying the ALPHA= option in the PROC REG or MODEL statement.

What is coeff VAR in SAS?

Coeff Var – This is the coefficient of variation, which is a unit-less measure of variation in the data. It is the root MSE divided by the mean of the dependent variable, multiplied by 100: (100*(7.15/51.85) = 13.79).

What does Outest do in SAS?

The OUTEST= data set contains each variable used as a dependent or independent variable in any MODEL statement. One observation consists of parameter values for the model with the dependent variable having the value -1.

What is PROC GLM in SAS?

The GLM procedure uses the method of least squares to fit general linear models. Among the statistical methods available in PROC GLM are regression, analysis of variance, analysis of covariance, multivariate analysis of variance, and partial correlation.

What is Proc logistic in SAS?

The PROC LOGISTIC statement invokes the LOGISTIC procedure. Optionally, it identifies input and output data sets, suppresses the display of results, and controls the ordering of the response levels. If you omit the DATA= option, the procedure uses the most recently created SAS data set.

What is PROC REG SAS?

Proc REG Statement names the SAS data set to be used by PROC REG. If DATA= is not specified, REG uses the most recently created SAS data set. requests that the crossproducts matrix be output to this TYPE=SSCP data set. NOPRINT. suppresses the normal printed output.

How does SAS calculate CV?

For a distribution, the coefficient of variation is the ratio of the standard deviation to the mean: CV = σ/μ. You can estimate the coefficient of variation from a sample by using the ratio of the sample standard deviation and the sample mean, usually multiplied by 100 so that it is on the percent scale.

How do you find the geometric mean SAS?

To compute the geometric mean and geometric CV, you can use the DIST=LOGNORMAL option on the PROC TTEST statement, as follows: proc ttest data=Have dist=lognormal; var x; ods select ConfLimits; run; The geometric mean, which is 20.2 for these data, estimates the “center” of the data.

Do you need a proc Reg statement in SAS?

The PROC REG statement is required. If you want to fit a model to the data, you must also use a MODEL statement. If you want to use only the PROC REG options, you do not need a MODEL statement, but you must use a VAR statement. If you do not use a MODEL statement, then the COVOUT and OUTEST= options are not available.

How are model statements included in Proc Reg?

The PROC REG statement is always accompanied by one or more MODEL statements to specify regression models. One OUTPUT statement may follow each MODEL statement. Several RESTRICT, TEST, and MTEST statements may follow each MODEL. WEIGHT, FREQ, and ID statements are optionally specified once for the entire PROC step.

When to use label in model Statement SAS?

For example, if you want to specify a quadratic term for variable X1 in the model, you cannot use X1*X1 in the MODEL statement but must create a new variable (for example, X1SQUARE=X1*X1) in a DATA step and use this new variable in the MODEL statement. The label in the MODEL statement is optional.

What does the output statement in SAS do?

The OUTPUT statement creates a new SAS data set that saves diagnostic measures calculated after fitting the model. The OUTPUT statement refers to the most recent MODEL statement. At least one keyword=names specification is required.
