a newbie question: can someone point me to where I can find information to get predicted values after running a multiple regression? Suppose I regress y on x1, x2 and x3. I would like to get a predicted value with x1=3, x2=4 and x3=8, for example. Thanks.

Hello Everyone , Good day , I was trying out Bluesky yesterday and I couldn't get the p-value for a hypothesis test. 2 sample t-test, Independent , to be precise. Any idea ? Thank you

I am trying to open a dataset but I get this error message and I cannot get the dataset to be 'active'. Moving the file to a folder with a shorter path (e.g. /Documents) does not help. I attach the file just in case. Any ideas?

Hi BlueSky Statistics Team! I find a problem using the linear regression model with factor regressors: as a simple example, if “Diploma” is used as a nominal factor with 4 categories, in the model formula the labels of the 3 categories are correct, but if “Livelli_spesa” is an ordinal factor with 3

I wish to run a "cost-sensitive" randomForest algorithm incorporating a "cost matrix" that reflects a custom loss function, with the option of minimizing the expected misclassification cost. I have read that R’s randomForest package doesn’t directly support multi-class or even binary cost-sensitive

I have two questions, [1] How do you turn off scientific notation from results, and [2] Is the decision tree tab running the same analysis as a classification and regression tree (CART) analysis?

Hi BlueSky Team. The menu option Summary > Frequencies produces a table where the numerical order is not correct (rows are sorted for Frequency and not for the variable M values): The problem doesn’t change using or not option “Sort in decending order” (note the typo). Best regards. Ma.C.

Is it possible for me to modify the dialog for for Decision Trees to add a weight variable? I know the rpart function can incorporate a weight variable. I realize that I can create custom dialogs for my own functions -- but is it possible for me to access the code for the Decision Tree dialog and cr
