How are gamma-ray burst radio afterglows populated?

We systematically analyze three GRB samples named as radio-loud, radio-quiet and radio-none afterglows, respectively. It is shown that dichotomy of the radio-loud afterglows not necessary. Interestingly, we find intrinsic durations ($T_{int}$), isotropic energies prompt gamma-rays ($E_{\gamma, iso}$) redshifts ($z$) their host galaxies are log-normally distributed for both except those GRBs without any radio detections. Based on distinct distributions $T_{int}$, $E_{\gamma, iso}$, circum-burst medium density ($n$) equivalent energy ($L_{\nu,p}$), confirm really better to be divided into dim bright types. However, it noticeable flux densities ($F_{host}$) from classes intrinsically quite similar. Meanwhile, point out sample also obviously different above two with observed, according cumulative frequency $T_{int}$ together correlations between $z$. In addition, a positive correlation iso}$ $L_{\nu,p}$ found in especially supernova-associated GRBs. Besides, this sample. A negative $z$ confirmed hold too. The dividing line short long rest frame at $T_{int}\simeq$1 s. Consequently, propose could originated progenitors.
