if the l decreases x the p decreases which of the following is the second channel that affects x? what type of equation do you use for a case with a complex causal structure? which channel of the system of causal behavior will be affected by the effects of x? which channel negatively affects x? how does p affect l how can l positively affect x which of the following is a function of the complex causal structure which channels affect x which channel positively affects x if the l decreases x the l positively affects x how does l affect x when it increases how does l positively affect x what is logical logic for complex causality which channels affect x? which channel of causal structure does l influence what is the second channel of causality? what is the two channels that l positively affects x what type of regression is used to prove complex structural relationships? which channel affects the x curve
