Density for the normal distribution

[yeahyeah]

The density of the standard normal distribution is given to us.

Do you think we need to memorize the density of the normal distribution? Which is:

f(x) = 1/[sigma*(2pi)^.5]*e^-(x-mu)^2/2sigma^2

One situation in which this might come up is finding the MLE for a normal distribution when you do not have complete individual data.

I am thinking any distribution that we will need will be provided for us, otherwise memorize it to save time during the exam.

[JMI]

Isn't it (2pi)^.5.

[yeahyeah]

Yeah (2pi)^.5

I just realized that the formula is basically given to us as the lognormal distribution. Just get rid of the 1/x and change the ln(x) to just x. Simple just need to remember to get rid of the 1/x

they give you this in the case of the standardized normal variable in the front of the manual.

[yeahyeah]

I know they give us the standard normal density, but that doesn't help all that much for the non-standard normal does it?
