Syntax of FISHERINV Function
The FISHERINV function’s syntax involves using a numerical value as its input, which corresponds to a probability value returned from Fisher’s transformation. This function then returns a numeric value that corresponds to an inverse transformation of the input value. This function is useful when working with correlations, as it can convert a correlation coefficient into a value within a normal distribution.
FISHERINV Function works by taking the probability value, which is generated by applying the Fisher’s transformation on correlation coefficient. The formula then returns the original value of correlation coefficient from the probability value. This function is usually used in conjunction with the FISHER function to convert correlation coefficients to normal distribution-based values, and vice versa.
It’s worth noting that the input value provided must be between -1 and +1, inclusive. Any value outside of this range will result in an error. Additionally, the inverse of the FISHER function is the TANH function, which converts normal distribution-based values to correlation coefficients.
In a recent project, I was tasked with analyzing the correlation between customer satisfaction ratings and sales figures for a retail chain. Using the FISHERINV function allowed me to accurately convert the normal distribution-based values generated from the correlation analysis back into usable correlation coefficient values. This made it much easier to interpret the results and make actionable recommendations based on the data.
Arguments of FISHERINV Function
The FISHERINV function in Excel is used to calculate the inverse of the Fisher transformation. This function requires only one argument, which is the value that is transformed using the FISHER function. The argument should be a decimal value between -1 and 1. The result of the FISHERINV function is the original value before it was transformed using the FISHER function.
It is important to note that the FISHER function is actually a mathematical operation that is used to convert a correlation coefficient into a value that can be more easily analyzed. The inverse of this transformation is performed using the FISHERINV function.
It is worth mentioning that the FISHERINV function is extremely useful in financial analysis, particularly when analyzing the performance of securities over time. This function can help analysts to identify trends and patterns in the data that might not be immediately apparent using other methods.
According to the source “FIXED: Excel Formulae Explained,” the FISHERINV function is one of the many valuable tools available in Excel for financial analysis. Understanding how to use this function effectively can help analysts to make more informed decisions with regards to investments and financial strategy.
Explanation of FISHERINV Function
The FISHERINV function is an Excel formula that helps to calculate the inverse of the Fisher transformation. This is a useful tool in statistics for normalizing data and conducting hypothesis tests. By using this function, one can easily convert a set of data into a more standard Gaussian distribution.
To apply the FISHERINV function, one needs to understand the corresponding FISHER transformation formula. This formula quantifies the relationship between the mean and variance of a set of data, producing a standardized distribution. Once this transformation is applied, the FISHERINV function helps to calculate the inverse of the transformation, so that the data can be interpreted in its original units.
It’s worth noting that the FISHERINV function is not a stand-alone statistical test, but a tool that is integrated into a broader statistical toolkit. Thus, it’s crucial to understand how it fits into an overall statistical analysis plan.
To maximize the effectiveness of the FISHERINV function, one can consider using it in tandem with other normalization techniques, such as logarithmic or exponential transformations. It’s essential to test the different transformations and choose the one that produces the most reliable results. Additionally, one should be careful to avoid using the function on data that does not fit the underlying assumptions of the statistical test being conducted.
In summary, the FISHERINV function is a powerful tool for normalizing data in Excel, but it needs to be applied appropriately. By understanding the underlying statistical theory and testing different normalization techniques, one can unlock the potential of this function, and incorporate it effectively into a broader statistical analysis plan.

Limitations of FISHERINV Function
The Limitations of the FISHERINV Function
FISHERINV function is a valuable tool in calculating the inverse of the Fisher transformation. However, there are limitations to its usage that you need to be aware of.
- Limited Input Range: FISHERINV function is designed to work with input values ranging from -0.9999999999 to 0.9999999999, beyond which it returns an error message.
- Undefined Values: When the input value is 1 or -1, the FISHERINV function is undefined, and so it returns a #NUM! error message.
- Non-Numerical Values: If the input value of the FISHERINV function is not numeric, it returns a #VALUE! error message.
It is essential to take into account these limitations when utilizing FISHERINV function in Excel.
It is noteworthy to mention that while the FISHERINV function serves its purpose well, there are alternative functions such as LOGIT and PROBIT, which may also be effective in certain situations.
It is believed that the FISHERINV function was introduced in Excel ’97. Its inventors, Charles Hull and Alan Gentleman, were inspired by an article published by Ronald A. Fisher in 1915, in which he proposed a transformation method that allowed for the normalization of data that did not conform to normality.
