T.990 =1.08

J,4958 =0.94 J. 199=0.68

and the aggregate value

Je — 0.02

The price mechanism gives a similar fit in the observation
range,

s(v”)=0.58 s(p)

Here the extrapolatory JaNus quotient (76) gives

(88) J.495)=0.69 J 19 =0.01

T1999) = 0.02

and the aggregate quotient

Ts =0.66

Using the three relations of the system (36) to generate forecasts
 by the chain principle, and applying the JANUS quotient
 (75) to the ensuing forecasts for price p,, the material gives
the following quotients

89)

JUD = 36 JU =1.56 JU) =0.04

and the aggregate

J=o0.02

According to (80) and (85) the Janus quotients (89) could be
expected to be higher than in (88), but the forecast refers to
only one sample series and here it so happened that the tendency
 did not materialize very clearly.
