Problem of a function I wrote
Hello everyone, I have been working on a code which simply repeatedly appends a number into a vector and write a file. However, it could not be properly implemented when I use it.

{nlme} Question about modeling Level two heteroscedasticity in HLM
Hello dear uesRs, I am working on modeling both level one and level two heteroscedasticity in HLM. In my model, both error variance and variance of random intercept / random slope are affected by some level two variables. I found that nlme is able to model heteroscedasticity. I learned how to use it for level one heteroscedasticity but don't know how to use it to model the level

Problem about zero
Hello, everyone, There's a problem about zero in R and I really need your help. I have a vector shown as x=c(0.1819711,0.4811463,0.1935151,0.1433675), The sum of this vector is shown as 1 in R, but when I type 1-sum(x), the value is not zero, but -2.220446e-16. I can accept that this value is quite small and could be seen as zero, but there would be a problem when it's not really

Multinomial Regression for Complex Survey
Hi Dear Rusers, I am working on a survey data with the "survey" package. The logistic regression and multinomial regression would be the main statistic method I want to use. I found that the svyglm function could be used to conduct the logistic regression with the complex design but not the multinomial regression. I wonder if there is any package or function in the "survey"
