'indirectly inferred' is correct and usable in written English.
It is a term that can be used to refer to the process of making an inference without the use of any direct evidence or facts. For example, John's silence during the argument indirectly inferred that he was not in agreement with the other participants.
APs may be regarded as locations and consequently the mobility patterns of the users (consisting of a sequence of visits to the locations) can be indirectly inferred.
Biological interactions are often indirectly inferred.
Although the structures of numerous KIR haplotypes have been indirectly inferred and deduced from population analysis and family studies [19], [25], [26], [27], [28], [29], [30], [31], complete determination of human KIR haplotype structures using direct methods has so far been limited to one A haplotype and two B haplotypes [25], [32], [33].
It can be indirectly inferred that the reduction in the number of foci was not simply a consequence of the slow expansion of foci from the observation that the number of foci on B149 plants were significantly lower than on C24 even at later time points (Figure 3, Panels B and C).
Blood volume is mostly indirectly inferred from measurement of arterial pressure, heart rate, CVP, and PAOP.
For instance, migration can be indirectly inferred using observations of genetic structure and a model formalizing how gene flow might have produced these observations.
The degree of binding of a drug to a receptor can be measured directly by the use of radioactively labeled drugs or inferred indirectly from measurements of the biological effects of agonists and antagonists.
For example, what are we to think of states of the universe prior to all observation of physical strata of the cosmos that cannot be observed directly or indirectly but only inferred as part of an overriding scientific theory?
These lag times were inferred indirectly, based on the time difference between when the plants appeared on planting lists and when they appeared in a published flora or sometimes in unpublished floristic data.
Seed size was inferred indirectly from the area of seed in profile.
The relative age distribution of gene duplicates within a genome can therefore be inferred indirectly from the distribution of silent substitutions.
