Hi,

I am analyzing multiple response questions in SPSS. I've figured out
how to use the multiple response frequencies (for dichotomy
variables), but I'm not sure what the results are telling me.

There is a Percent column, and a Percent of Cases column. Does anyone
know the difference betweeen the two columns? I know that the percent
of cases are the percent of total "occurrences" for that particular
variable.

But what does the Percent column represent?

Thanks for your comments.

i wrote a program to open pre-saved data sets constructed as a matrix
and saved as .sav files.i want to make a loop and each time open one
file and make some calcluations. i do not want to make it as a macro.
i don't know what is the correct way to open the file within the
matrix. my files named 1.sav,2.sav,.... please help.
my syntax is
*set mxloops=100000.
MATRIX.
compute alpha= 0.
loop i=1 TO 9.
mget /FILE=CONCAT('D:\Doaa\work\',i,'.sav')).
compute mean= CSUM(x)/NROW(x).
compute cov=(1/(NROW(x)-1))*(SSCP(x)-NROW(x)*(t(mean)*mean)).
compute y=make(nrow(x),1,0).
compute b=make(nrow(x),1,0).
compute h=10.21.
LOOP J=1 TO NROW(x).
compute y(j)= (x(j,:)-mean) * inv(cov) * t((x(j,:)-mean)).
DO IF (y(j)>=h).
compute b(j)=b(j)+1. ...

Hello, I am trying to do a post Hoc (I do not want to use the
contrasts) on a one-way repeated measure ANOVA. However, when I click
on the post hoc button, all the options are greyed out, meaning that I
cannot choose anything.

My data is this:

Participants are shown ten sets, where each set consists of five
alternatives. Each time they have to choose one of the five
alternatives. In SPSS, I have created a variable for each alternative
(5 variables). In addition, the data is the number of times each
alternative was chosen in total. So one specific alt can only be
chosen maxim 10 times since there are only ten sets.

When I go to Analyse--> General Linear Model --> Repeated, I choose my
five variables as within variable with five levels. When I go to
define, I define the five variables, however when I click on Post Hoc,
I cannot choose anything in that window.

Hope I made sense.....

Sincerely Yours

Hi all,

I have been presented with an analysis of a 2x2 (2 groups x 2
treatment) crossover design study, based on the syntax provided by
SPSS in their knowledgebase (#26277), which I have copied below. The
syntax uses the GLM procedure to analyse a model with treatment, order
and treatment*order (ie, carryover) effects.

The syntax assumes that the dependent measure is taken at baseline,
after period 1 and after period 2, and that it is the two difference
scores from baseline that are used in the analysis. However, in this
analysis the researcher has kept the three separate measures in the
analysis rather than converting to change scores. Ie, their syntax
starts:

GLM baseline placebo treatment BY order ...

Am I correct in assuming that by not converting to change scores that
the analysis is now actually invalid? In particular I would think that
the tests for the period effect and carryover effect would no longer
be testing what we are interested in? In anyone able to confirm that?

Thanks,
Kylie.

Dear All,

This is my first time in the newsgroup, so everyone forgive me in
advance for being a newbie.

Also: this may be a problem that everyone knows how to fix, but I'm
having a lot of worries trying to figure it out.

I've a file in access with 1. records that have a unique identifier
(one per school), and several fields with fixed data, but have a
varying number of test data, for example, one caseid might have valid
data for only one subgroup, on four categories, but another school
might have valid data for nine subgroups on all four categories. A
last category tells me what format the previous categories are:
percent, count, etc.

the structure of the data is like this:

year caseid category1 category2 category 3 type of data
2007 001 yes 2 3 count
2007 001 no 3 2 percent

where I've got perhaps nine entries for some ids and only two for
others; and the data are not in cases by rows.

Greetings all. I have SPSS Grad Pack 14 and had the class in Spring
2006. I am putting together my final thesis project and need to
interpret about 117 surveys with 25 questions each and multiple
responses in each question.

I have run some Cross tabs and some frequency tables. The little
manual I got with the sofware is not very indepth, I have found the
tutorials in the program somewhat helpful. But since it has been so
long since I have had the class I am really unsure............!

The professor I had for the class in 06 is awesome but I am now doing
my project long distance and hate to keep bothering him. Are there
any SPSS tutors/coaches ect that could help me? Obviously I would pay,
I really need some guidance.

An email note or a response on this site with any suggestions would be
much appreciated.

i want to generate 10000 data set of size 1000 in spss.but when
running the syntax no data generated and appears

the Warning # 232

i tried to use the statment
set miterate=1000000. but another error that the parameter should be
positive???????!!!!!!!
if any one know the solution to this problem, please send me as soon
as possible.

my syntax was:

Hi all,

I am new to SPSS and want to compare the effect of treatment with
rainfall intensity. I have 10 rainfall event data with corresponding P
in runoff. I want to know upto how much intensity of rainfall, the
treatment is working well.Could u plz suggest me whether I can use
ANOVA ? IF so could u plz
say me the procedure in SPSS.

Thanks,
Jery
