How to calculate sMAPE Subtract the actual value from the absolute forcast Square the result Find the square root of the previous result (step #2) sMAPE = Square Root ( F – A)^2 In general when comparing forecast methods, the smaller the sMAPE the better. <h2>How to calculate sMAPE in r</h2> <h3>Use the Metrics Package.</h3><p>Assume …

Why is the two-tail p-value always twice the one-tail p-value in a t-test? In the t-test output below, notice that the two-tail p-value is 0.66852 while the one-tail p-value is 0.33426. The two-tail p-value is twice the one-tail p-value. Why is this true? The two-tail p-value is defined as P > |t|. That is, the …
