Huston and Nicholsonâs tempestuous, on-again, off-again relationship lasted 17 years, from 1973 until, after hoping for almost two decades to marry and start a family with him, she learned that he would instead be having a child with a younger woman.
A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve. An Order 2 polynomial trendline generally has only one hill or valley. Order 3 generally has one or two hills or valleys. Order 4 generally has up to three.
The bottom line is that if you use Excelâs trend line feature to apply a trend line to a set of data in a graph â¦. â¦ experiment with the options to find something that is a reasonable fit â¦. â¦. and have Excel put the equation for the line on the graph â¦. â¦. you need to be careful if you use the equation to predict data, especially with higher order polynomials. It could be pretty tempting to write a formula that used the trend line equation and assume it was correct. And technically, it is correct.
