We find that a preliminary classification of LINERs ’ energetics may be made in terms of the FIR-radio correlation of Wolf-Rayet galaxies .
The AGN- or starburst-supported LINERs can be distinguished by their FIR-to-radio ratio , Q \equiv L ( 1.4 { GHz } ) / L ( 60 \mu { m } ) > or < 0.01 .
It is interesting to note that almost all the LINERs with inner rings might be starburst-supported , indicating reduced AGN activities compared with those of the AGN-supported ones .
We also find that a shock-heating phase for the warm dust component might be important for some starbursts at the burst age of \geq 10 ^ { 7 } yr , with Q < 0.001 .
