For example, when the “temporary linear regression equation by the least squares method” is stored in the arithmetic equation memory 38, it is calculated in the following procedure. In the following description, the case of “day data” is shown as a representative.

That is, the expression stored in the arithmetic expression memory 38 is (“weight value” ω) = (constant k) + (constant m) × (“day data” t). When the average weight value data of n ′ pieces is represented by x ′ and the day data corresponding to x ′ is represented by t ′, a constant k and a constant m
Are respectively calculated by the following equations.

(Constant k) = {x ′} (x′t ′) − {t ′} x ′ ² } / ｛(Σx ′) ² −n′Σx ′ ² … (constant m) = {Σx′Σt′-n ′ {(X′t ′)} / {({x ′) ² −n ′} x ′ ² }... The calculated constants k and m are substituted into the above equation to obtain a correlation approximation equation. Substituting t = 1 into the correlation approximation formula ω = k + mt in which the constants k and m are substituted, and the calculated ω becomes the predicted weight value ω of the next day. Further, the constant m calculated earlier becomes the tendency value m.

In step S83, the predicted weight value ω becomes “−3σ
≦ ω ≦ + 3σ ”is determined.
If the predicted weight value ω is within the range, the determination is YES and the process proceeds to step S90. If the predicted weight value ω is not within the range, the determination is NO and the process proceeds to step S84. If the predicted weight value ω is within the range, the process proceeds to step S90 with the current predicted weight value ω as the predicted weight value ω. If it is not within the range, step S84-
