The phrase "alterations to model" is correct and usable in written English.
It can be used when discussing changes or modifications made to a specific model, whether in a scientific, engineering, or artistic context.
Example: "The team implemented several alterations to the model to improve its accuracy and performance."
Alternatives: "modifications to the model" or "changes to the model".
Below we discuss some possible alterations to the model, which might contribute to greater model realism, albeit whilst incurring a loss of generality.
Primary alterations to the model include addition of small seedling demography, soil saturation effects, shade adaption of tree photosynthesis, and browsing algorithms.
We therefore tested how various alterations to the model's design could affect the predicted decrease in directional selectivity under high-frequency stimulation.
This study provides new insights and alterations to previous models and offers a complex dataset, which will be further analyzed towards increasing our biochemical understanding of the adaptive mechanisms to N starvation and recovery in Chlamydomonas.
After a panic at the turn of the millennium about the impact on their industry of online shopping, bricks-and-mortar stores settled into making only modest alterations to their business model or, ostrich-like, trying to ignore it.
Besides making specific genetic or epigenetic alterations to cells or model organisms, genome-editing tools, especially CRISPR/Cas9, have also been developed for high-throughput genetic screenings (Fig. 1C).
Our aim was to include these components with the least alterations to the Drosophila model in a way that all key experimental observations in control and MO experiments in Nematostella could be reproduced and thus generate a minimal viable model of BMP signaling maintenance in Nematostella after symmetry break (see the Supplemental Experimental Procedures for details).
A variety of analyses linking model variables (e.g. scale and shape parameters from the Weibull distributions) to incidence, recurrence and prevalence are presented in Appendix II, see Additional file 2. This Appendix also contains a series of simulations, each with n = 25 replications showing the effect on point prevalence of alteration to various model parameters.
A Sobel-Goodman test [81] was performed, both with and without alterations to fit logit models, as described by Mackinnon and Dwyer [82], yielding almost identical results.
