21 cze 2021 · An arcsine transformation can be used to “stretch out” data points that range between the values 0 and 1. This type of transformation is typically used when dealing with proportions and percentages. We can use the following syntax to perform an arcsine transformation in R: asin(sqrt(x))
The arc-tangent of two arguments atan2(y, x) returns the angle between the x-axis and the vector from the origin to (x, y) (x,y), i.e., for positive arguments atan2(y, x) == atan(y/x). Angles are in radians, not degrees, for the standard versions (i.e., a right angle is \pi/2 π/2), and in ‘half-rotations’ for cospi etc.
24 lip 2012 · I'm trying to arcsine squareroot data lying on [-1,1]. Using transf.arcsine from the metafor package produces NaNs when trying to squareroot the negative datapoints. Conceptually, I want to use arcsin(sgn(x)√|x|) i.e. square the absolute value, apply its previous sign, then arcsine transform it.
The arcsine transformation in r does not just use a single built-in function rather it is two embedded functions. Those functions are the arcsine function and square root function. They work together to produce arcsine transformation.

Inverse Trigonometric Functions. In the previous post R Lesson 32: Basic Trigonometry, R Style, we learned about the three basic trigonometric concepts-sine, cosine and tangent. Today, we’ll explore inverse trigonometric functions such as the arc-sine, arc-cosine and arc-tangent.
