内挿補間の種類について質問させてください.
使用しているver.は2.18.28になります.
デフォルトでの内挿補間はTINとIDWだけだと思いますが,ArcGISではTrendという補間があります.
このTrendをQGISでも使いたいなと考えているのですが,同じまたは同様の内挿ができる補間方法があれば教えてください.
コンソールを使ったやり方はよく分からないのでプラグインなどで対応できればと思っております.
ご助言お願いいたします.

使ったこともない状態で憶測も入ってしまいますが、、
プロセッシングツール → SAGA の「Polynomial Regression(多項式回帰)」というのが近いかな?と思いました。
Plynomという回帰手法を選ぶところで
[0]: 1次多項式
[1]: ???
[2]: 2次多項式
[3]: 3次多項式
に該当するような気がします。

adachiさんのご指摘で合っているように思います。
