WebMar 20, 2024 · Here is why you cannot just remove a value from a variable without removing the whole observation where the value is: PCA is based on linear algebra--it works only with matrices and vectors--i.e. numerical variables. This means you can't just remove a value from a variable while keeping the other variables as you are working with matrices.

WebFirst, you'll need to reformat your data, changing it from a "wide" format with each variable in its own column to a "long" format, where you use one column for your measures and another for a key variable telling us which measure we use in each row. econdatalong <- gather( econdata, key ="measure", value ="value", c("GDP_nom", "GDP_PPP")) WebFor this purpose, there exist three options: aggregating more than one categorical variable, aggregating multiple numerical variables or both at the same time. On the one hand, we are going to create a new categorical variable named cat_var.
I am trying to use a smooth.spline transformation for my explanatory variables in glm (logit regression). I get the error because smooth.spline cannot work with NAs. Here is my code: LogitModel <- glm(dummy~ smooth.spline(A) + B + C ,family = binomial(link = "logit"), data = mydata)
