Hope this helps. Just recently I noticed, that Excel was slow in just simply copy and paste an number from cell A to B, without any formulas or anything else.
With slow I mean it takes 1 second for copying and one second for pasting, which is annoying when you have to do this a couple of times a day. When I was trying to track down the problem I found that disabling Xrealstats Add-In solved the problem. Copy and paste returned to be as quick as usual, meaning there is no time delay.
Are you aware of that issue AND can you help me solving that issue? Have you tried to restart your computer? Since then I restarted the computer several times. I tried all the three RealStats version I could found in my storage: 7.
This 1-second delay in copy and paste actions is introduced whenever and only when one of the above XRealStats add-in is enabled.
The effect is instantaneous, i. Of course, it persists even after Excel or Windows get restarted. To me, is a minor issue and I can ignore this cost, in particular if compared to the immense benefit I get from having RealStats enabled in Excel! Just let me know… …but, in any case, thank you for you effort and your wonderful software! Federico, Thank you for your kind remarks and for your information about the performance impact.
How much RAM memory do you have on your computers? Do you still see the effect when you only have Excel open and no other application? Notably, this delay only seems to affect the copy and past actions. I do run into a slight problem with my Office I was able to pull up the Real Statistics tool. I wanted to do a cross-correlation analysis, but I did not find it in the Time S tab or anywhere else. Can you help me with this? Hello, It is in the Time S tab.

Dear Charles! I was very happy when I found the www page after a lot of searching. True, I am of Hungarian nationality, I do not understand English.
I would like you to help me with the following problem: I want to know the statistics of a static time series, so I started using this great program package. I calculated a lot of ARIMA p, 0, q characteristics of the time series and recorded some of their characteristics for later analysis. I also plotted the SSE values of the two processes. Always stopped with an error. I also attach the Excel file. Sincerely, please help me solve my problem.
Thank you in advance for your help. Please note that we can only communicate through Google. Sincerely: Barnabas e-mail: kissbarnabas56 gmail. Kedves Charles! This is a very good software that helps many people in the world. With regards. Hi Charles, thank you for this neat resource!
Any ideas? Hello Jaclyn, I just tried it using my computer and I had no problem using Chrome. What version of Real Statistics are you trying to download?
Hola Charles, la presente es para hacerle la siguiente consulta: 1. Hello Velasco, Sorry, but Real Statistics does not yet support negative binomial regression. It does support Poisson regression and I expect to add support for negative binomial regression shortly.
Hi Gabriele, Thank you very much for sharing this with us. Hi Charles, in the holt winter excel you have provided you have created a seasonal parameter, Can you please explain more on this parameter. When i mark it to 4 the forecasting begins after 4 rows and when i make it to 12 it creates after 12 rows. So can you explain the significance here.
We are trying to immitate this using holtwinter function of R but the start period of the excel and the start period of R holtwinter and similarly the end period of excel add in and end period of R doesnt match. Any information around this or any similar question if some one asked before, any advice would be very helpful. If the seasonality is 4, you can only start to get information that relates to the seasons after one cycle namely 4 time periods have passed.

Principles of the Analysis of Variance Analysis of variance ANOVA is a tool used to partition the observed variance in a particular variable into components attributable to different sources of variation.
Select a grouped data table where rows categorize the data according to one factor, and columns categorize them according to the other factors. Interactions up to order 4 can be included in the model as well as nested and random effects. XLSTAT has an automatic device to find nested factors and one nested factor can be included in the model. Four methods are proposed for model selection : Best model, Stepwise, Forward, Backward Test assumptions : a Shapiro-Wilk test is performed on the residuals.
