distribution of the specified form.
“FDIST” (page 254) The FDIST function returns the F probability
distribution.
“FINV” (page 255) The FINV function returns the inverse of the F
probability distribution.
“FORECAST” (page 256) The FORECAST function returns the forecasted y
value for a given x value based on sample values
using linear regression analysis.
“FREQUENCY” (page 257) The FREQUENCY function returns an array of how
often data values occur within a range of interval
values.
“GAMMADIST” (page 259) The GAMMADIST function returns the gamma
distribution in the specified form.
“GAMMAINV” (page 260) The GAMMAINV function returns the inverse
gamma cumulative distribution.
