calculation problem
...hange index) which includes pasitive and negative values.
Certainly following codes could not be correct:
MAPE= ( (sum (abs( (y-fittedvalue) /y)) )/ n) *100
MAPE
y: real value
because sign of negative values are neglegted. If we code it as following:
absy=abs(y)
signy=sign(y)
absfittedvalue=abs(fittedvalue)
signfittedvalue=sign(fittedvalue)
MAPE= ( (sum (abs( (absy-absfittedvalue) /absy)) )/ n) *100
MAPE=MAPE*signy*signfittedvalue
also would not be correct. But how can we cope with this difficulty?
For remainder DS could be got by:
DS=...

help to setting a multiple (linear) regression model with a 5% significance level (threshold) for the inclusion of the model variables.
Dear Researchers,
someone know the right syntax to chose a 5% significance level (threshold)
for the inclusion of the model variables in a multiple (linear) regression
in backward way?
I set the formula in this way, but I don't know to choose the 5%
significance?
lmodelV <-
step(lm(formula=MyFormula[[1]],data=LR.train),direction="backward")
thanks in advance gianni
