Cultivation breeders are certainly familiar with experimental design material, including complete randomized design, group randomized design, and others. Of course, with different terms and conditions. But this time…

• ## SARIMA ARIMA : The Twins of Time Series

Those of you who are used to using it must be familiar with R-square or R-square adj, where this one indicator explains the goodness of the model issued…

• ## Find here a secret tip: Ironing of Regression.

Ironing of Regression. The need for data fitting techniques in regression is because regression is synonymous with linear. This is because the standard pattern of regression is a straight line. Where Y = a +bx +e … with a as a constant, b is a coefficient that reflects the relationship between variables x and Y,…
