If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. The array known_x's can include one or more sets of variables. If the array known_y's is in a single row, then each row of known_x's is interpreted as a separate variable.Īn optional set of x-values that you may already know in the relationship y = mx + b

If the array known_y's is in a single column, then each column of known_x's is interpreted as a separate variable. The set of y-values you already know in the relationship y = mx + b The TREND function syntax has the following arguments:

If const is FALSE, the parameter a is set to 1.=TREND(known_y's,, , ).

If const is TRUE or omitted, the parameter a is calculated normally,.

const (optional) is a Boolean value specifying whether to force the parameter a to equal 1:.

If you omit new_x's, it is assumed to be the same as known_x's,.

new_x's (optional) are the new x-values for which the GROWTH () function should calculate corresponding y-values:.

In any case, you should provide the known_x's or array that has the same size as known_y's, These variables cannot be omitted for the correct calculation of a power trend.

known_x's (optional) are independent data values:.

known_y's (required) are dependent data values,.

The array function LOGEST () calculates the power curve that fits best the known data and then returns an array with statistics describing the trend line:

The array function LINEST () calculates the linear trend that fits best the known data and then returns an array with statistics describing the trend line: number (required) is a number to take the natural logarithm of.The LN () function is the inverse of the EXP () function and returns the natural logarithm of a given number: number (required) is a power that e is raised to.The EXP () function returns the result of the constant e raised to the power of a number:
