包中的无向链接：kitz，库：bayesnet

Question

$phi$对于此网络，我想要一个无向虚线链接，而不是和之间的虚线箭头$\sigma_y$。我不知道该怎么做。

谢谢

        \node[latent, above=of phi] (f) {$f$};
        \node[obs, left=of f] (y) {$\bf{y}$};
        \node[latent, below =of y] (sigma) {$\sigma_y$};
        \edge {phi} {f};
        \edge {f, sigma} {y};
        \plate[inner sep=0.25cm, xshift=-0.12cm, yshift=0.12cm] {plate3} {(phi) (f) (y) (sigma)} {W}; %
        \edge [dashed] {phi} {sigma};
    }

只需将选项-（无箭头的箭头）添加到相关边缘即可。这将覆盖默认设置。
