Oct 13, 2004 · vce saturation voltage What is the meaning of Vce(sat)? If Vce(sat) of a BJT is 0.6V does it mean that the Vce must exceed 0.6V to ensure the transistor is in active region? Thanks

Jan 4, 2018 · Yes, it sounds like -vce (robust)- is appropriate here, and does what you want. And Stata will interpret it to mean -vce (cluster ID)-. And I don't think anyone will worry that 122 clusters are too few.

May 5, 2021 · Priyesh: under -regress-, -vce (robust)- accounts for hetreoskedasticity in residual distribution, whereas -vce (cluster)- accounts for residual autocorrelation. Hence, you should take a look at your dataset first and then decide which way to go with your standard errors (default; robust; cluster): there's no hard and fast rule (as, unfortunately, it's often the case in life).

Jan 6, 2012 · Vce (sat) is roughly proportional to collector current. So, for your circuit, deduce Vce (sat) from the value closer to your 20mA load, that is, Vce (sat) for Ic = 150mA.

Feb 25, 2010 · Saturation Vce is a value in the datasheet of a transistor, and it does not change. Its the voltage across C and E when the given (maximum, saturation) current is flowing through C an E (and Vbe sat. is applied on base). If you don't know it, and you have no other information about the specific transistor, you can only measure it. Ideally Vce is zero in saturation. NPN are most used for ...

Jun 14, 2018 · Within my analysis with the vce (robust) my variable is signifiact and with the vce (cluster var) command the variable becomes insignificant. Can someone explain to me the difference?

Apr 23, 2021 · Guest: as an aside to others' helpful replies: 1) under -xtreg- (I assume you're using this -xt- command) both -robust- and -cluster- options do the very same job (as they tell Stata to adopt a cluster-robust standard error); 2) running regressions with different specifications and obtaining different resulst comes with no wonder at …

May 1, 2014 · Hi everybody I'm confused about Transistor saturation current,as i know Vcc=Vce+Ic*RL where Vcc:The source voltage Vce:Collector to emitter voltage RL:Load Resistance and at saturation Vce=0 Volt my confusion is, Is saturation current depend on the load resistance "as the equation prove" ...

Dec 11, 2018 · Hey all I am trying to get the mean and the standard deviation from a variable. I know how to do it without svy: sum lnhourly if immigrant==1

Apr 16, 2016 · Saiming: - you may want to compare the results of both -estat hettest- and -estat imtest, White- on your data; otherwise, you can impose -vce (robust)- standard errors. However, I would also consider different test apart those focused on heteroskedasticity, like in the elaboration of the following toy-example:
