Tests of distribution

> Iron <- subset(spearhead, subset=Mat=="2")
> Uniform <- runif(19,0,600)
> ks.test(Iron$Date,Uniform)

Test for whether Maxle has a normal distribution with either stipulated mean and standard deviation or those from the sample.

Graphical comparison:

> qqnorm(Maxle)
> qqline(Maxle)

Kolmogorov-Smirnov test:

> Normal = rnorm(40)
> ks.test(spearhead$Maxle,Normal)
