Question




where i-1, , N denotes household and J 1, ,J denotes heat systems. ai is the dummy variable of alternative j and income is the income of household i. We estimate the model by setting "heat pump as the base. mlogit(depvar" ic+oc lincome, H, reflevel 'hp') > m . = summary () Call: nlogit(formula-depvar- ic + oc income, data-H, reflevel = "hp", method- "nr", print,level - O) Frequencies of alternatives: hp ec er gc gr 0.055556 0.071111 0.093333 0.636667 0.143333 nr method 6 iterations, Oh:Om:0s g, (-H)"-1g = 6.27E-06 successive function values within tolerance limits

Explanation / Answer

Decision rule : If p value is smaller then that variable is more fovourable

Base on the above rule, the followng is the explanation

=> p value for ic = 0.0136

=> p value for oc = 0.00000749

if we observe this, p value for oc variable < p value of 'ic' variable

so oc is more significant and strong relation with income

comparing with oc, ic variable is less significant

Hence OC variable is more favourable and IC variable is less fovourable
