tests for homoscedasticity

[junebeetle]

Hi,

I have a question on homoscedasticity, are these tests similar to normality tests like Shapiro wil. W test.
I guess I am looking for tests to look for homoscedasticity in my data.

Thanks

the tests are for detecting heteroscedasticity and there are many:
white, breuch-pagan, arch test etc.

Levenne's test too tests homoscedasticity/homogeneity of variance. It is available on SPSS.
