transform

Hello everyone, As a very begginer in SPSS I would ask you for help with some transformation from table A into table B. I have to recode values of "brand" variable into columns and make 0-1 variables. I can do it in this particular case in this simple way: compute GREEN_CARE=0. compute...

I am doing a single linear regression and multiple regression, but I have a question about my independent variable. My independent variables (X) are between 0 and 100. Some of my hypothesizes is that "A high X will lead to a lower Y" High X = value above fifty to hundred and Low x =...

Hello, everyone, I need a little bit of help salvaging the data from a questionnaire. One of my colleagues applied a questionnaire, but inadvertently, instead of using the original 5-point Likert scale (strongly disagree to strongly agree), he inserted a 6th answer into the scale. And, to...

I asked this question a while back and never found an answer. After reading my multilevel book I realized the answer from the logit link reading: ((1 - (1/(1 + exp(x)))) * 2) - 1 This should take any real number between -Inf and Inf and transform it to between -1 and 1. I think. I came up...

Hey everyone, I have a data set which is log normally distributed and want to detect outliers, so far I used a threshold approach: vector contains the values of interest. outlier detected if: value > ((2*(median absolute deviation(vector))/0.6745) + median(vector) My problem is: is...

Hello! I have some variables which are scale but their limits vary. Namely, the one has range from 1 to 30, the other from 2 to 5, and so on. Is there any way to tranform them (or recompute them) in such a way that they will be standardised and will all have the same range? :confused:

I am working with invoice data and analyzing thousands of prices and part numbers on invoices. I think I have to convert the data into individual data points to be able to sample it correctly and do calculations. Is there a way to convert or transform this data without writing a script to do...

I have several different variables. The majority of the variables were positively skewed and therefore I did a log10 transformation to make them more normal. However, two of the variables were quite normal already and now after log10 are more negatively skewed. In order for me to do some...
