Hi,
I´m trying to run this function:
z<-lm(mrall~beertax+mlda+jaild+vmiles+unrate+perinc, data=essay).
I don´t know why this keeps appearing:
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
NA/NaN/Inf in 'y'
In addition: Warning message:
In storage.mode(v) <- "double" : NAs introduced by coercion
I have the following dataframe:
str(dataset)
'data.frame': 336 obs. of 11 variables:
stato : int 1 2 3 4 5 6 7 8 9 10 ...
