Test Normality
Good Night
I made different test to check normality and multinormality in my dataset,
but I don´t know which test is better.
To verify univariate normality I checked: shapiro.test, cvm.test, ad.test,
lillie.test, sf.test or jaque.bera.test and
To verify multivariate normal distribution I use mardia, mvShapiro.Test,
mvsf, mshapiro.test, mvnorm.e.
I have a dataset with almost 1000 data and 9

Optimization max likelihood problem
hello all,
I am getting wrong estimates from this code. do you know what could be the problem.
thanks
x<- c(1.6, 1.7, 1.7, 1.7, 1.8, 1.8, 1.8, 1.8)
y <- c( 6, 13, 18, 28, 52, 53, 61, 60)
n <- c(59, 60, 62, 56, 63, 59, 62, 60)
DF <- data.frame(x, y, n)
# note: there is no need to have the choose(n, y) term in the likelihood
fn <- function(p, DF) {
z <- p[1]+p[2]*DF$x

p-value or the t-test value
Hello,
How can I print out the p-value or the t-test value for coefficients estimated from a likelihood function.
Thanks
