The No Trend Time Series Model Is Given By:
A) $y _ { t } = \beta _ { 0 } + \beta _ { 1 } t + \varepsilon _ { t }$

The no trend time series model is given by:

A) $y _ { t } = \beta _ { 0 } + \beta _ { 1 } t + \varepsilon _ { t }$
B) $y _ { t } = \beta _ { 0 } + \varepsilon _ { t }$
C) $y _ { t } = \beta _ { 0 } + \beta _ { 1 } t + \beta _ { 2 } t ^ { 2 } + \varepsilon _ { t }$
D) $y _ { t } = \beta _ { 0 } + \beta _ { 1 } \ln t + \varepsilon _ { t }$
