Normal probability plot in r studio
WebGenerates a probability plot for a specified theoretical distribution, i.e., basically a qqplot where the y-axis is labeled with probabilities instead of quantiles. The function is mainly intended for teaching the concept of quantile plots. Web2 de jan. de 2024 · The half-normal distribution has density f ( x) = 2 θ π e − x 2 θ 2 / π It has mean E ( x) = 1 θ and variance V a r ( x) = π − 2 2 θ 2. The parameter θ is related to the standard deviation σ of the corresponding zero-mean normal distribution by the equation θ = π / 2 / σ. If θ is not specified in the above functions it assumes ...
