Dear Sir,
Our bank purchased an product called Inforsense years ago, there is a
department using it to conduct a data analysis using the "Bestfit"
function called "General R". As it is understood that the "General-R" is
the "R-Intergration" plugin developed by R-Project, we would like to ask
some questions on the difficulty that we encounter.
During our statistics re-performance, we found that even if the data are
considered to be normally distributed by "General-R", the statistic
result on the confidence interval determination is still greatly
different from the result calculated by EXCEL spreadsheet*. As we are
not very familiar with the Statistics and not sure how many kinds of
statistic models for data of normal distribution there are, thus we
would like to inquire if the R is using different methodology on the
confidence interval determination from the EXCEL? Thank you very much.
*P/S- We just simply use the Excel Function ("Mean", "Stdev" and
"Confidence") to calculate the confidence interval for the data.
Thanks& Regards,
