The LSMEANS are computed as follows: LSMEAN ROW1 = [(2) + (2) + (2)] / 3 = 2.00 LSMEAN ROW2 = [(2) + (5) + (6)] / 3 = 4.33 LSMEAN Variable N Mean Std Dev Minimum Maximum ------------------------------------------------------------------------------ PRICE 26 6651.73 3371.12 3299.00 15906.00 MPG 26 20.9230769 4.7575042 14.0000000 35.0000000 REP78 26 3.2692308 0.7775702 2.0000000 5.0000000 FOREIGN 26 0.2692308 0.4523443 0 A detailed description of these statistics is provided in the section Combining Inferences from Imputed Data Sets and the section Multiple Imputation Efficiency. http://interopix.com/standard-error/standard-error-standard-deviation-divided-by-square-root.php

See www.stattutorials.com/SASDATA for files mentioned in this tutorial © TexaSoft, 2007-13 These SAS statistics tutorials briefly explain the use and interpretation of standard statistical analysis techniques for Medical, Pharmaceutical, Clinical Trials, Using options on the PROC statement We can use the data= option to tell proc means to tell SAS what data file will be used to perform the means procedure. Example proc surveymeans data=CARS1 STD; var **horsepower; BY** make; ods output statistics=rectangle; run; proc print data=rectangle; run; When we execute the above code it gives the following output: Result for make CLASS indicates the variables used for categorical variables. https://support.sas.com/documentation/cdl/en/statug/63347/HTML/default/statug_surveymeans_a0000000223.htm

It is not the standard error of the difference of two rows' LSMEANS used by the PDIFF option to compare LSMEANS. Let's examine some examples. Introduction This module will illustrate the general syntax of SAS procedures. More examples We have illustrated the general syntax of SAS procedures using proc means and proc reg.

Here we show that it is possible to use proc means with no options at all.

Options on a proc statement come right after the name of the proc, but options for subsequent statements must follow a forward slash. The hypotheses for this test are: Ho: μLoss = 0 (The average weight loss was 0) Ha: μLoss ≠ 0 (The weight loss was different than 0) For example, the following All rights reserved. http://support.sas.com/kb/24/984.html PROC MEANS DATA=auto N MEAN STD ; RUN; The output, shown below, shows just the N, mean, and standard deviation, just as we requested.

Relevant. Taylor Series Method When you use VARMETHOD=TAYLOR, or by default if you do not specify the VARMETHOD= option, PROC SURVEYMEANS uses the Taylor series method to estimate the variance of the Recipients acknowledge and agree that **SAS Institute shall not** be liable for any damages whatsoever arising out of their use of this material. Beginning in SAS 7, all SAS procedures use ODS (the Output Delivery System) which among other things allows the output of any table to a data set.

The examples include how-to instructions for SAS Software. http://www.stattutorials.com/SAS/TUTORIAL-PROC-MEANS.htm PROC REG DATA=auto ; MODEL price = mpg / STB; RUN; The output is the same as the output above, except that it also includes the portion shown below that has Proc Means Standard Error DATA auto ; input MAKE $ PRICE MPG REP78 FOREIGN ; DATALINES; AMC 4099 22 3 0 AMC 4749 17 3 0 AMC 3799 22 3 0 Audi 9690 17 5 Standard Error Of The Mean WINKS SDA Statistical Software and Graphics -- A simple and affordable (starts at $75 (download edition)) statistical software program that will help you analyze, interpret and write-up your results.

PROC MEANS ; RUN; Here you see the results of the means procedure from the auto data file. http://interopix.com/standard-error/standard-deviation-standard-error-confidence-interval.php In addition, SAS Institute will provide no support for the materials contained herein. Mathematically it measures how distant or close are each value to the mean value of a data set. By default,SAS uses the last data file created (i.e., auto) and it provides means for all of the numeric variables in the data file.

The OUTSTAT= data set does not contain the results from the ESTIMATE statement. The table also displays a 95% confidence interval for the mean and a t statistic with the associated p-value for testing the hypothesis that the mean is equal to the value The following statements use the UNIVARIATE procedure to generate sample means and standard errors for the variables in each imputed data set: proc univariate data=outmi noprint; var Oxygen RunTime RunPulse; output More about the author T for H0: Pr > |T| Std Error of Parameter Estimate Parameter=0 Estimate diff r1 vs r2 -2.33333333 -2.36 0.0348 0.98997827 diff r1 vs r3 -2.66666667 -2.90 0.0123 0.91831631 diff r2

It also displays the degrees of freedom for the total variance. PROC FREQ DATA=auto; RUN; If we use the page option, proc freq will start every table on a new page. End of this tutorial, part 1, Click to continue or Go To Index of Additional SAS Tutorials For more information...

The t-statistic associated with the null hypothesis is –2.79, and the p-value for this paired t-test is p = 0.027, which provides evidence to reject the null hypothesis. go

Standard Error The standard error of the mean is the square root of the estimated variance. The keyword VAR requests the variance of the mean.

If you specify the PDIFF option and omit the ADJUST= option, the default method is to analyze all pairwise comparisons using t-tests providing no p-value adjustment.

Then, for the Row1-Row2 difference: t = [2 - 4.33] / sqrt(2.4615)/3*sqrt[(1/1+1/2+1/2)+(1/3+1/4+1/1)] = -2.33 / sqrt(.98) = -2.35 The p-value for t=-2.35 and 13 error DF is 0.034.

These estimates are then combined to generate valid univariate inferences about the population means. SAS and all other SAS Institute Inc. From what we have learned, we would expect that proc freq would have: - Options on the proc freq statement that would influence the way that the tables look. - Additional
