 DDSolver Issue [General Sta­tis­tics]

Dear All,

i can't reproduce the variance-covariance matrix in modell depended approaches results.
Based on the math, it would be easy to calculate, but i can't reproduce with excel data analysis and with my linear algebr knowledge.

The variance-covariance matrix is essential, to calculate the mahalonobis distance, what show the similarity.

How does calculate DDSolver the variance-covariance matrix?

If you need, i can send you my calculations in mail.

Hi László,

see this thread. I recommend bootf2BCA v1.2 for [image] (see there).

» How does calculate DDSolver the variance-covariance matrix?

Sorry, no idea.

 DDSolver Issue

Hi László,

» Thank You Helmut!

Welcome. Aleksander Mendyk published bootf2BCA v1.3 on 2021-05-08.

Lines 394–405 of F2_boot.R are funny. It would list close to 800 installed packages on my machine. :-D
Consider to comment it out and use

options(width = 52)
devtools::session_info()

instead. On my machine:

 DDSolver Issue

Helmut, i have found an easy way to calculate the variance.covariance matrix:

https://stattrek.com/matrix-algebra/covariance-matrix.aspx

Calcualting the matrix with this way, the result is same like excel data anaysis toolpak.

"The method dependet approaches" calculates an other result.

I hope, DDSolver calculates correct as well, but i don't know ddsolver uses some other factors as well.
