FISHERINV(number)

• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle number} is the value to find inverse of fisher transformation.

Description

• This function gives the inverse of the Fisher transformation.
• We use this to test the correlations between set of data.
• The Inverse of the Fisher transformation is: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle x= \frac {e^{2y-1}}{e^{2y+1}}} i.e Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle y=FISHER(x)} , then $FISHERINV(y)=x$
• It can be used to construct a confidence interval.
• A confidence interval (CI) is a type of interval estimate of a population parameter and is used to indicate the reliability of an estimate.

This function will give the result as error when the Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle number}
 value is non-numeric.

Examples

1. FISHERINV(0.6389731838) = 0.56419999998
2. FISHERINV(0) = 0
3. FISHERINV(0.1234) = 0.1227774315035342
4. FISHERINV(1) = 0.761594155955765
5. FISHERINV(-0.4296) = -0.4049869686465480
