your articles are very clear! To do this, divide each expression in the entire problem by 2: 2x ÷ 2 = x; 4 ÷ 2 = 2; and 10 ÷ 2 = 5. And, I’m very happy you found the blog to be helpful! For example, if we said y is I’m learning this stuff at uni and have come across a question which has completely confused me and wondered if you could help? This condition is an interaction effect. Or are p values and R square enough to indicate the fitness of the MRQAP model.I have to apologize, but I don’t know MRQAP models well enough to provide an answer. – olidev Mar 21 '12 at 9:27 Your problem now reads x = 14. Thank you:).Hi, I’m sorry my posts caused you to lose some sleep last night, but I love your analogy about light bulbs going off! expression and an equation. we set these variables to be these things, this whole But, you probably don’t need to worry about R.Hi, I know this may seem to be a very simple question, but is there a difference between R and r? Was the negative coefficient that was significant for one of them?I found your way of explanation very helpful.Currently in the process of submitting my thesis… I am confused about the results that i got and I need your help…,In my Multiple regression table: 2 B coefficient values are negative,X1 (Promotion and Internal Recruitment) —– Beta coefficient = -.029; whereas it’s p value = .763.I interpreted it as this shows an inverse relationship; where if X1 (Promotion and Internal Recruitment) increases by 1 unit, holding other variables constant, then the value of Y “employee engagement” will decrease by 0.029.however for my other variable: HR policy the Beta coefficient is negative but the p value is less than 0.05.I interpreted it as If X2 (Human Resources Policy) increases by 1 unit, the value of Y will decrease by 0.183.MY MAIN QUESTION IS REGARDING THE SECOND VARIABLE I.E. Your results are statistically significant, which means you can conclude that your coefficient is significantly different than zero (i.e., an effect exists in the population).Amazing post Jim!! By standardizing them, the coefficient represents the change for a one standard deviation change in the IV. 2 to the third power, which is negative 2 times Example: sin(−θ) = −sin(θ) is one of the Trigonometric Identities. The absolute value of the t-value determines whether the test is significant for the typical two-sided test. Next, we simplify both sides of the equation. "Solving" only gives us possible solutions, they need to be checked!Divide every term by the same nonzero value,Sometimes we can apply a function to both sides (e.g. the difference between expression and equation. really just a statement of value, a statement of Thank you so much for this as it helped clear up some things in my mind as I prepare a research paper.Hi Tracey, you’re very welcome. That’s a different matter. However, if you have a meeting at 9AM, you’ll be late! DataTip. thanks!Thanks for the clarification. Again, you’ll need to make that determination on a case-by-case basis.I’ve just recently written two posts about outliers that you’ll probably find helpful. Some equations are true for all allowed values and are then called Identities. or is there any link/archive where I can view each article publish date for citation?I’m glad this article was helpful for you! Removing this variable would potentially bias the other coefficients. It is really helpful.Hi Kim, thanks so much for your kind words! square both sides). like the square root of x plus y and then minus x, like that. In that case, the hypothesis tests based on them are not valid.2. or should i just drop these columns or should i proceed with these variables in my dataset?Those are called indicator variables and indicate the presence or absence of a particular characteristic. Been studying this stuff for weeks, now I finally get it thanks to your post. My case is MRQAP model, do I have to plot residual plots to indicate the fit of the MRQAP model?
