Question: A stochastic process ({X(t), t>0}) has the one-dimensional distribution [left{F_{t}(x)=P(X(t) leq x)=1-e^{-(x / t)^{2}}, x geq 0, t>0 ight}] Is this process weakly stationary?

A stochastic process \(\{X(t), t>0\}\) has the one-dimensional distribution

\[\left\{F_{t}(x)=P(X(t) \leq x)=1-e^{-(x / t)^{2}}, x \geq 0, t>0\right\}\]

Is this process weakly stationary?
