I was checking some models and I found some variable as the following :
effect of faculty quality:effect of academic staff quality on university reputation f(ratio of current to historical perceived academic staff quality)
effect of academic staff quality on university reputation f : (0,-0.1)-(2,1)],(0,-0.25),(0.07,-0.25),(0.24,-0.24),(0.49,-0.178

so what is F mean?
