how that the sample mean ¯xt = 1t∑ti=1 xi can be written in the form:new estimate = old estimate + gain ∗ news
Question
Solution 1
Claro, vamos a resolverlo paso a paso.
Primero, recordemos la fórmula del promedio muestral:
[ \bar{x}t = \frac{1}{t} \sum{i=1}^{t} x_i ]
Queremos expresar esto en la forma:
[ \text{nuevo estimado} = \text{estimado antiguo} + \text{ganancia} \times \text{novedad} ]
