In Excel the MAP function is part of the new dynamic array functions introduced in Excel 365 and Excel 2019 with the appropriate updates The MAP function allows you to perform a calculation on each element in one or more arrays and return an array of the results Heres how to use it
The MAKEARRAY function in Excel is used to generate an array by applying a formula or logic that you specify across a defined number of rows and columns This function is useful for creating dynamic arrays with custom computations without needing to fill in each cell manually It was introduced with the Excel version that supports dynamic arrays like Excel 365 or Excel 2019 onwards
The LOWER function in Excel is used to convert all the letters in a text string to lowercase This is particularly useful when you want to standardize text data to ensure consistency regardless of how the original data was entered Heres how you can use the LOWER function
The LOOKUP function in Excel is used to search for a value in a range and return a corresponding value in another range There are two main forms of the LOOKUP function the vector form and the array form Heres how to use each
The LOGNORMINV function in Excel is used to calculate the inverse of the lognormal cumulative distribution function at a given probability In simpler terms it gives you the value of the variable at which the cumulative probability matches a given probability assuming the data follows a lognormal distribution
The LOGNORMDIST function in Excel is used to calculate the cumulative lognormal distribution of a given value This function has been replaced with newer functions in more recent versions of Excel such as LOGNORMDIST but you can still use LOGNORMDIST in versions of Excel that support it for compatibility
The LOGNORMDIST function in Excel is used to calculate the lognormal distribution of a dataset This function can be particularly useful when youre modeling data that is positively skewed such as financial returns or an assets price
The LOGINV function in Excel is used to calculate the inverse of the lognormal distribution It is useful when you want to find the value x for a given probability mean and standard deviation of the logarithm of x
The LOGEST function in Excel is used to perform an exponential regression analysis by fitting an exponential curve to your data and calculating the parameters of that curve Its commonly used for data that you suspect follows an exponential growth or decay pattern
The LOG10 function in Excel is used to calculate the base10 logarithm of a given positive number This function is useful for various mathematical and scientific computations especially when working with exponential scales like measuring sound intensity in decibels or comparing magnitudes of large numbers
