pwrSEM a-priori Power Analysis for SEM

[@yulinliu850]

Wonderful tool. Thanks James for the information!

[@julioalejandronavoni6754]

Super useful! Thank James!

[@rover8734]

Do you have any information about Power standards? For example, 8 and above means good.

[@Gaskination]

That is correct. 0.80 and above is considered good. Here is a review of the key references: chatgpt.com/share/74c8423e-ac77-4b98-a97f-049d1ed9a73d

@ james gaski. Sir i have finite population and my sample size comes 750 sir i dont have any supporting refrence where minimum criteria is 600 i found many refrence klines ( 2002) he said minimum sample size should be 200 hair et al (2010)said no of items in q *10 Sir if u can give me any supporting refrence in social sciences where this 700 is taken plz i am in immnese need coz i couldnt find any one

If you have 750, then you have more than enough. No need to cite anything if you have so much sample. The trouble would be if your sample was too small.

@Gaskination i need citation for that refrence plz include any authors name year whivh i can give as supporting refrence

[@Gaskination]

@@hameemislam753 I don't think I understand what you're trying to support. Are you trying to justify 750 sample size as sufficient? To do this, just do a power analysis and then cite something on power analysis, like: -MacCallum RC, Browne MW, Sugawara HM (1996) Power analysis and determination of sample size for covariance structure modeling. Psychological Methods 1(2):130-149. -Tanaka JS (1987) 'How big is big enough?': Sample size and goodness of fit in structural equation models with latent variables. Child Development 58(1):134-146. -Wolf EJ, Harrington KM, Clark SL, Miller MW (2013) Sample size requirements for structural equation models: An evaluation of power, bias, and solution propriety. Educational and Psychological Measurement 73(6):913-934.

[@Gaskination]

You can find lots of literature for SEM here: www.smartpls.com/documentation/

hello james...am missing something...what is is this tool and why?

[@Gaskination]

power analysis is to see how much sample size you'll need to properly conduct a study (to avoid false negatives). This tool is for figuring out how much sample size you'll need for a study you plan to analyze with SEM.
