How to estimate my model?

[Fatz]

It/Kt-1 = B0 + B1 Tobin’s q + B2 St /Kt-1+ B3 St-1 /Kt-2 + B4 St-2 /Kt-3 +
B5 St-3 /Kt-4 + B6 St-4 /Kt-5 + B7Size+ B8 Cash flow

For my model I have to see the effect on Investments. I am taking Tobin's q, sales, asset size and cash flows as independent variables. I have collected data of 5 years. Can somebody plz tell me how to estimate this on views? This would be panel data analysis. I have randomly picked some firms on the basis of availability of data so, not all the firms in a particular sector are included in the sample. Would I use Random effect model? Also, what about 'K" as a denominator? Can somebody plz explain how would I use "K" in my calculations and estimations? Also, plz help me in understanding how to run the regression on EViews as I am new to it.
