WebThus, a more rigorous quantitative analysis is performed by regressing the FLS coefficients against a trend variable and a trend- structural change interaction variable as follows: (5) βˆt = σ 0 + σ 1δ t + σ 2ψ t + ω t , where β̂ t is the estimated time varying FLS coefficient from equation (4), σ 0 is an intercept term, σ 1 and σ 2 are the coefficients on the trend variable … WebTownsend regime which depends on the electrode material and on the nature of the filling gas used.
